    PROBLEM IN DISPLAY OF WIND VECTOR USING SMS

    Hi smita, I believe what is going here is that your contours are covering the vectors in the upper portion of your mesh. To make your vectors show up above the contours, you can either add transparency to the contours in the display options or change the Origin/Offset options in the vectors tab of the display options to tell SMS to draw the vectors at a higher location. Hope this helps.
  2. Hi NicT, Unfortunately, SRH-2D currently only utilizes a single core. If you buy a computer with multiple cores, SRH-2D will still only use one of those cores. I believe there will be a parallel version of SRH-2D that will utilize multiple cores in the future, but I'm not sure when that will be.

    2dm mesh cannot be linked to SRH-2D simulation

    Hi Pablo, If the mesh won't link to the SRH-2D simulation that means that the mesh is incompatible with SRH-2D. To make it compatible with SRH-2D, you'll first need to make sure that the mesh has linear elements. If it doesn't, you can convert to linear elements by selecting "Elements | Linear <-> Quadratic". The other thing you'll need to do is make sure the model it is associated with is "Generic Mesh". You can do this by selecting "Data | Switch Current Model" then selecting "Generic Mesh". You should be able to link the mesh to the SRH-2D simulation after making these changes. If it still won't link, there may be something else about the mesh that makes it incompatible with SRH-2D that you'll need to address.

    HorizonID

    The "Auto-Assign Horizon" tool referenced on the wiki is currently only available in GMS (the Groundwater Modeling System). When using this tool, it is important to review the results since they can often have problems with complex borehole data. Another method such as classifying the data based on material or unit descriptions will need to be used to populate HorizonIDs in a BorePoint feature class.
  5. It would be nice if it was possible to copy the state of the Log Xform checkboxes in the MODFLOW parameters list. One GMS customer had several hundred parameters that were negative (CHDs) so he had to toggle off each Log Xform checkbox manually and this capability would have been very helpful in doing this task.

    Run Code Convergence Issues

    Hi Ryley, I'd suggest that you start troubleshooting by reviewing the mesh geometry. You can use the mesh quality display options and/or the mesh quality scatter set to check mesh elements and find poorly formed elements or other similar issues. I'd also recommend reviewing mesh element elevations by turning on and inspecting elevation contours. The other thing I would look at are your boundary conditions to check for reasonableness and/or errors. If there are issues related to any of these items you may be able to set the time step to a slightly larger value.

    Mesh resolution based on Topography

    M, I would recommend looking into the scalar paving density mesh generation method in SMS. This method uses the values specified at each point in a particular scatter set (referred to as a "size function") to determine mesh element sizes. The "Size Function" SMS 12.1 tutorial demonstrates how scalar paving density can be used in SMS.
  9. One of the GMS training course participants in the August 2014 Provo course suggested that we give the user the option to adjust the size of macros/buttons/tools in the GMS interface. He mentioned that he would be interested in having this option when working on larger screens with high resolutions.
  10. It would be nice to add some text to the legend that reported that the "Fill below" and/or "Fill above" contour options were selected. A user suggested that "and below"/"and above" be appended to the min/max values in the legend to tell the user that all values below/above the min/max value were the same color. From the GMS user: "When I have the ‘fill above’ option on, is there a way of editing the legend so that it says this? At the moment it stops at the 2 m maximum I have told I to plot, but would like the legend to say something like ‘2 m and above’. I can do this in ArcGIS, not I can’t see if this can be done in GMS."
  11. A GMS user would like to GMS to remember the current set up of the grid and use it as a default when mapping a grid frame to a new 3D grid. He pointed out that grids are typically only changed by a small amount, or not at all, and it would be useful if those numbers would be retained.
  12. Many of our users live in areas that display times and dates in different formats than what GMS uses. It would be helpful to allow the user to specify the time/date settings to control how GMS displays times and dates, similar to the "Time Settings" window in SMS.

    blank value? like NaN in MATLAB?

    Hi Younes, You can specify a range of values for SMS to contour in the display options that would exclude the values above a certain value. To do so: 1. select "Display | Display Options" 2. select the "Scatter" item in the upper left 3. select the "Contours" tab 4. select "Specify a range" 5. enter the maximum value you'd like SMS to contour, then deselect the "Fill above" checkbox to the right of the Max field 6. Select "OK" SMS should now only display contours that are below the maximum value you specified.

    Node strings

    Hi karunakar, I'm not sure why the land boundary nodestring would have suddenly disappeared. Could you verify that all the nodestring types are active in the nodestring options window that results from selecting the "Options..." button to the right of "Nodestrings" in the "Display | Display Options | 2D Mesh" window? Also, was there something that happened between the time that you saw the land nodestring and when it disappeared? Can you select a nodestring with the select nodestring tool where the land nodestring used to be?

    Import from web - aerials in b/w

    All Terraserver aerial photos are in black and white. The SMS "Import From Web" tutorial shows a color image just before you download the image from Terraserver, but this image is from the Virtual Earth Map Locator window, which is in color in SMS. The Virtual Earth Map Locator is only used by SMS to identify the location and extents of the area to download data from. The actual aerial imagery is downloaded from Terraserver. In the next release of SMS (SMS 11.1), there will be better tools to download images (including aerial images) similar to what WMS 9.0 uses.
