    Include an option to export/save materials from the "Edit | Materials" window. The user who suggested this to us asked: "Is there a way to save the materials designations (by this I mean the name, color, pattern, and so forth of the soil units or horizons) so that these can easily be imported into a new project. I realize they are saved if I save the project I created them in, but I’d like to be able to just import this information if I create a new project rather than having to rebuild the designations."

    Unfortunately, there is not an automated method to export well transient pumping data for all wells in the format you'd like it to be in. However you can export out the pumping data for each well (if you have them assigned as feature points in the map module) by following the steps below. 1. Double click on a feature point representing a well with transient pumping data 2. Select the button in the "Flow rate" column with the three dots to bring up the XY Series Editor 3. Select the "Export..." button 4. Specify the file name and location and then select "Save" I realize that with many wells this will be a tedious process. I am therefore submitting this as a feature request to the GMS developers. I apologize for the inconvenience.

    Chris, When inserting a new mesh into an old mesh, be sure to leave a transition zone between the two meshes - the "hole" you are appending the new mesh into should be larger than than the new mesh. If that doesn't work, please contact technical support and send them your files so we can see if there is a problem. Thanks, John

    Hi Matt, I am not aware of SMS ever being able to export out 3D polyline shapefiles. However, you could export the map data as a dxf/dwg file by right clicking in the "Project Explorer" and selecting "Convert to CAD", then selecting "File | Save As" and changing the "Save as type:" to "AutoCAD Files (*.dwg;*.dxf)". You can then add this AutoCAD file into ArcMap using the "Add Data" tool and the lines will be loaded as Polyline Z features with the elevations specified in SMS.

    Great! this solves the model checker error message. I made a simplified version of the femwater model and compared it to a modflow one. - brief one layer two bc - constant head (h=2 and h=0 sea level) top and bottom elevation derived from boreholes data (scatter data) refined elemnts I attached the following screen capture show computed head contouring: 4-1 = modflow with 1 layer grid (top and bottom elevation interpolated), plus obs wells, everything seems ok 4-2 = modflow with grid (mean values for top and bottom elevation), plus obs wells, everything seems ok 4-3 = femwater with 1 layer grid (top and bottom elevation interpolated), plus obs wells. The 4-3 model show the total head that is the same as head in modflow. Is it correct? Why the contouring 4-3 is so different? I run the model with different starting heads and the computed heads depends from the initial condition. I coudn't get the obs wells (in conceptual model - obs point) to have the computed head value. I tried to fix their z elevation to match the 3d grid elevation but without success. Thanks dlattuada

    There is no really simple way to do this but there is a round about way. You will need to create two points(mesh nodes) in the mesh module and then select them. Right click on them and select interpolate options Here you can specify spacing. You then have to select save as and choose tabular data file as the file type select the right data to be saved i.e. x, y coordinates With the new file, click and drag the new file into SMS. It should bring up the import wizard Select next Change the SMS data type: to feature points There you should have refine points which you can choose to refine the in the j direction

    Hi all', I would like to simulate the outflow rate out of a saturated compacted fill material 120 m by 60 m pit area (1.8 m depth) with 4 layers units (clay/gravel. Leakage is detected at the leachate extraction and detection sumps, at the bottom of the pit. The fill material- could be saturated during time of placement (since there was 160 mm of rainfall during this time). Therefore, there has been no recharge/rainfall since capped. It is well capsulated with clay liners (sidewall/ bottom of the pit)in place. The water table in the area is deep 12 m below surface. The task is to figure out if the outflow/leakage is coming out of the saturated fill material or it is leakage from surface (which is unacceptable). I am planning to simulate the outflow rate and match with the observed flow rate at the leachate extraction sump (coming out after 3 months since placement, this could be due to delayance effect?. Do we expect a constant outflow rate through out or varies exponentially with time? How long do we need to pump out if the leakage is coming out of the filled mataerial. How can I simulate this problem this using MODFLOW? Thanks Muluadwa

    I apologize for the incomplete steps. Here are the complete steps: 1) Whiles the vectors are displayed, right click in the white area in the project explorer and select Convert to CAD. This should create many cad layers, one of which should be a vectors CAD layer. 2) Right Click on CAD Data in the project explorer and select Convert | CAD to Map. This will create many layers in the map data, one of which will be of the vectors. 3) Go to File | Save As and change the file type to shape file. 4) Click save and then select arcs. Note that the heads will be hollow. If you would like the heads to be filled then you can try going to Feature Objects | Build Polygons after the above step 2 and then in step four saving the polygon shape file as well. Creating a bunch of polygons may cause issues though.

    Rob, I'm not sure what could be going on here. Right away, I would suggest lowering the timestep and see if that makes a difference. I would try hourly timesteps and then even a 1 minute timestep if you're still getting errors. If this doesn't solve the problem, I would suggest looking through the unsteady flow troubleshooting chapter in the HEC-RAS user's manual (p. 8-57 "Model Stability"). This has a number of suggestions for things to check to fix the problem (cross-section spacing, computation time step, etc). Sorry I can't be of more help. If these suggestions don't help, you could also send the model to us and have us look at it for you, but that doesn't fall under normal tech support. If it comes to that, let me know and we'll work something out with you. Thanks, Clark

    Hi John, We work extensively with Breakwaters in Bouss2D. I'm not clear where your problem lies, so I will respond to the original queries from Benjamin: 1) The BOUSS2D manual and associated technical notes indicate that porosity layers can be used to simulate breakwater effects, however we have had limited success with this - note our work is predominantly with rubble mound breakwaters. We generally simulate breakwater effects using damping strings - the manual and Bouss2D page on the SMS Wiki (http://www.xmswiki.com/xms/SMS:BOUSS-2D) provide a chart which can be used to estimate the required damping parameters based on a desired reflection co-efficient for the breawater. Be careful using damping strings in smale scale applications (e.g. entrances to small harbours/inlets where damping strings have the potential to reduce the effective entrance width). 2) These standing wave effects occur when waves reflected form the structure interact with the incoming wave train. It is important to note that these standing wave effects do occur in reality (this effect is known as clapotis http://en.wikipedia.org/wiki/Clapotis). If your wave maker is too close to the breakwater, or if your reflection coefficient for the breakwater is too high (see number 1 above), these effects may become amplified in a non-realistic manner (this may also cause the model to crash). Some methods to avoid this include: - use realistic reflection co-efficients - keep your wavemaker at least 4 wavelengths (rule of thumb) from any structures in your domain - consider using an internal wavemaker with damping on the seaward boundary - if you are not concerned with the region in between the wave maker and the seaward side of the breakwater, consider applying some strong damping to stop the formation of standing waves. As noted above, there is some good info on the Wiki regarding these issues (http://www.xmswiki.com/xms/SMS:BOUSS-2D). As a word of caution, remember that these standing wave effects are real before trying to eliminate them. In our work, we sometimes have to carry out additional post processing and analysis to separate the incoming and reflected wave trains. Regards Joel JFA Consultants

    I am running the flow in Femwater. When I input the compressibility of the medium(the soil is gravel). So I input the compressibility factor 1.0e-007. But my model can’t run accuracy. Then I find something in card type “MP2”. (MP2 1 0.4058 0.4058 0.4058 0.0 0.0 0.0 2.0e-008 0.3543 1.0) The 0.3543 is the value that I input about saturate moisture content (α). Why this value appear here? How do I input the right compressibility factor in the model?

    Correct me if I am wrong, but I understand that van Genuchten characteristic curves, while realistic and commonly used, present difficulties in practice. They are highly non-linear, which means that a fine spatial scale is required to achieve convergance and/or good solutions. Vogel & Ippisch (2008) Estimation of a critical spatial discretization limit for solving Richard's Equation at Large Scales. Vadose Zone Journal 7(1) 112-114. So how do people handle this?

    The 2.0E-008 is the compressibility, the 0.3543 is the porosity (=saturated moisture content), the 1.0 is the effective porosity ratio (which is supposed to be on the MP5 card, but GMS puts it in the wrong place). I am not sure why the compressibility is different from the value you entered (1.0E-007) though. Maybe there is another MP2 card?

    I can confirm thet there seems to be a bug in GMS regarding calculating van Genuchten unsaturated material properties for FEMWATER. I calculated van Genuchten curves for "Loamy Sand" using the equations and parameters in the FEMWATER manual (page 52-53). When I compared these to the curves produced by FEMWATER for the same situation, it seems that GMS is not adjusting the alpha parameter for the length scale. The FEMWATER table of alpha values is given in 1/cm, this needs to be changed if a different length scale is being used. According to the GMS wiki http://www.xmswiki.com/xms/GMS:FEMWATER_Model_Input: "Note also that the units of the van Genuchten 'alpha' have been 'hard-wired' into GMS. Because of this the values should always be entered in units of 1/cm. GMS will convert to the model units accordingly." There are two ways to specify van Genuchten release curves. Either use a preset soil type or enter the parameters manually. If you enter the alpha parameter in units of 1/cm both ways give the same result. However, the wiki quote above claims that GMS converts alpha to the appropriate length scale before calculating, but it is not doing this. You can workaround this bug by entering the parameters manually with alpha in the correct units.

    Dear colleagues: I am finding a cilly problem: if I try to have a run with some of the files classified into directories (for instance, bathymetry under "bathymetry" directory, etc,), I get errors when running, because the model can't find the data files. It seems as if the general file does not store the path to the files. The problem dissapear if I have the full set of files in the same directory. But from time to time, I use to share files in different runs, and this forces me to copy all of them in the run's directory. This can produce errors, in the case I modify one of the files: I should proceed to copy it all the times I am using it. Thanks, Jose M.

    It seems to make sense that with a smaller community, a single forum is adequate, and when the community grows larger, the single forum can be split into more specific sub-forums. However, when we switched to the new Invisionzone forum hosting service, we created a separate MODFLOW forum. Our reason for creating it initially was mainly because we could. Now we're wondering if we jumped the gun. What do you think? Should we have just one GMS forum, or stick with a GMS and a MODFLOW forum?

    Sorry to hear of your troubles. We aren't aware of problems with dragging nodes. If you can find a set of repeatable steps, please contact our technical support and give them a description of the steps so we can get this fixed. There were a couple changes in SMS 10.0 that affect memory use. One change would give some savings to overall memory use was how we allocated storage. This gives some memory savings but the bigger effect was faster building of scattersets. If you are talking about switching from SMS 9.0 to SMS 10.0, you would also have the changes impacted by the development of SMS 9.2. I can't remember all of the details of the changes between these versions, but something along the way might have increased our memory use for some kinds of data. Are you saying that in SMS 9.0, you could have the original scatter set and 5 sub-sets all in SMS at the same time? What size of a scatterset are you working with? Off the top of my head, I'm not sure that I have a definitive recommendation. You could try filtering your scatter set. If you use a small angle like 1 or 2 degrees, it will only remove points that really do not contribute much of anything to the shape of the surface. However, if you are running up against the memory limit performing the filter may itself cause you to exceed the memory limit. In the next version of SMS, we plan to distribute a 64-bit version of our software which may help alleviate some problems like this. You will want a computer with lots of available RAM to work with large datasets in this version. The 64-bit version has pros and cons. It allows you to access far more memory with a single process, but the data storage mechanism requires more memory. We hope that this version will be released in beta sometime in the next month or two. Sorry that this is not an immediate help. I would be interested to look at your data to try some things to see if I could come up with some more solid recommendations. Could you contact our technical support and get them your data? If that is possible, it would help us give you better guidance for your situation.

While I followed the documentation as closely as I could, and was confident that I had set everything up correctly, the model would not run, and kept giving the following error message: forrtl: severe (157): Program Exception - access violation I thought that perhaps the problem was with using the CMS-FLOW outputs, so I tried to force the particles with outputs from the ADCIRC tutorial simulation.
