  2. Materials Pattern Properties

    We can select Color and Pattern in GMS Materials. But in Pattern Properties dialog, there are only 23 patterns. I think they are not enough .Can I add another pattern?

  4. Index is out of range

    Hello friend, Do anyone know the cause of the error message: Index is out of range . This happens usually when i convert my conceptual model to MODFLOW. My model is relatively big one. it consists of 5 layers with about 55000 active cells. The maximum number of stress period, which I can define is 27. If I try to increase the Stress periods number I get this error message. is there a limitation for the Stress periods number depending on the number of active cells or the complexity of conceptual model. Thanks
  5. Hi there, I'm having a problem related with assigning specified flow boundary conditions to my UGrid / Modflow-USG model. The error appears when I do the '' Map to MODFLOW'' option while converting my conceptual model to UGrid numerical model. I have read the helping document saying that If you want to use ''Specified flow boundary condition'' the UGrid must be a stacked grid. A stacked grid is one in which there is no vertical discritization of layers and the horizontal discritization of all layers is the same. (i.e. the Index of Vertical Sub-Discretization (IVSD) in the UnStructured Grid Discretization (DISU) package could be set to -1) (See the Figure attached). Firstly, I did not understand what this means and how to find the IVSD in the DISU package and set it to -1 to be able to use specified flow boundary condition. In my model there are 2 groundwater divide boundaries which must be zero flow and 2 formation boundaries where the aquifer feeds from neighboring formations with a specified flow value. If I ll have to change my specified flow bound. cond. with something else or If there is a way to use them, could you please help me to find the solution? Thank You!
  6. CAD to Solids

    The convert to cad command only converts what is visible. Try turning on the faces of the solids and then converting to cad.
  7. Interpolate to MODFLOW Layers

    Looks like a bug. We will get it fixed, added to the test suite and post an update.
  8. CAD to Solids

    I convert the solid in GMS to CAD using Convert TO CAD. Then the cad objects are 3d faces. But when I open it ,and use CAD to solids, it failed!
  9. Interpolate to MODFLOW Layers

    There is a tutorial in Rasters about using rasters for interpolation and visuallization in GMS. There is an example in page 11 of 12 about Interpolate to MODFLOW Layers. I open the file in Tutorials\GIS\Rasters\point.gpr. When I select all the rasters in the Project Explorer and Interpolate to MODFLOW Layers, the MODFLOW layers elevations have some problems. If I convert all rasters to 2D Scatters ,then interpolate the 2D Scatters to MODFLOW Layers, there is no problen about the MODFLOW Layers.

  11. CAD to Solids

    If there are 3d faces defined in the CAD file then those can be converted to solids.
  12. Exporting Observation Values with MT3D

    This feature does not exist in the current version of GMS.
  13. Scatter point menu / merge scatter point set

    Notice that the link you mention is for the SMS software. This feature is not currently supported in GMS. However, you can submit an item to the feature requests to add it.
  14. CAD to Solids

    When I open a three-dimensions cad object in GMS, for example a cube, I cann't convert the cad object to feature objects or to Tin or to Solids. It seems only the two-dimenssion object can be converted. Also,the CAD to Solids cann't do anything. If only the two-dimenssion object can be used ,what the 'CAD to Solis' can be done?
  15. Import HEC-HMS to WMS

    WMS does not currently have the option to import an HMS file. If you have an HEC-1 file, you can read this into WMS using the HEC-1 menu. There is no reason we could not support an option to import an HMS file, and I have added this request to our list of tasks, but implementing the option to fully import an HMS file will take some time. Your only option right now, if you want to get it into WMS, would be to try to duplicate the model in the WMS interface. Chris

  18. Import HEC-HMS to WMS

    Hi! I've got a complet HEC-HMS projekt wich was generated in HEC-HMS 4.1. How can I import and edit it now with WMS 10.1?? Thanks!!
  19. If I wanted to export the simulated watertable elevations through MODFLOW, I would select MODFLOW->Observations->Export Trans. Obs. I would like to do the same thing with my MT3D data. Do you know if there is a way to export simulated concentration values for observation points? Thanks!
  20. Scatter point menu / merge scatter point set

    As a follow up, I am able to merge from the project explorer window but not from the scatter menu as described here http://www.xmswiki.com/wiki/SMS:Scatter_Menu I would like to be able to set the priority options for the merge and this does not appear possible from the right click in the project explorer route...
  21. I'm trying to merge two scatter point data sets (which I've done before), but the merge option is grayed out and unavailable under the scatter point menu. Any ideas as to what I need to do to make it available? I'm sure its something simple...
  22. SFR Package - Arc interpolation control

    Hi Sean -- I did the SFR2 package construction all in GMS. The segments have to be in order - from upstream to downstream and the GMS MAP module programming does a good job of this. The trick I found was having a good DEM and matching flowlines to work with. Even with all the prep work we did, there we still some segments that had to fixed by hand.
  23. SFR Package - Arc interpolation control

    Thanks again - I spoke with my GIS guy yesterday and it seems that getting the segment starting and ending elevations wouldn't be that difficult. I'll just have to figure out how best to get them into GMS. Did you do it via cut and paste into the dialog box for the segments, or through a MODFLOW input file? Right now, GMS looks to a binary file for the array. I think I was recently successful in getting an input file to ignore the binary file, but in another case, I was not successful (I don't recall the details on which package it was), so just curious as to which way you went.
  24. SFR Package - Arc interpolation control

    I'm running with about 8,000 segments in the larger of the 2 model I'm working on. I don't think the type of topography is that important, just get the closed depressions out and make the flowlines match the DEM
  25. PEST, SVD and SVD-assist

    Hi Jonas, If you try to generate random parameter values with this utility you have to decide how to describe the variability in the generated values. If you choose, that random values should obey (log)normal distribution you must specify its properties for each ajustable parameter (e.g. uncertainty of that parameter). This is done by specifing uncertainty file (see section 2.5 in PEST manual part II). Within this file uncertainties can be supplied on a parameter-by-parameter basis; alternatively one or a number of parameter covariance matrices can be supplied. If you want to avoid all this, try selecting (log)uniform distribution for the random values. Then you should be able to generate the uniformly distributed values without any problems. Hope it makes sense
  26. SFR Package - Arc interpolation control

    Thanks, Bruce. I totally agree that the SFR2 package is better than drains or rivers when you are actually trying to get the correct water balance in a watershed. That's why we're using it. The issue is that the region is mountainous, so using one segment for a 30,000 m long stretch of stream/river doesn't put the streambed at the right elevation for much of that length. I like your thought of using GIS, but like you said, it would be pretty high-level work.....I may have to go that route though if I don't figure out a better way to do this in GMS. Do we know if there is an upper bound to the number of SFR2 segments allowed? Without accounting for elevation changes, I will have around 100 segments in the drainage basin. If I wanted to be precise in accuracy, I could easily get to 1000 segments (I wouldn't likely if I did it manually, but if I went the GIS route, I would shoot for high accuracy).
  27. SFR Package - Arc interpolation control

    Hi Sean -- What we did recently to get the SFR2 package running was mainly a GIS exercise. We simplified and put all of the streams in a "blanket" type surficial layer that covers the entire active model area. Then we put a Digital Elevation Model (DEM) together of the land surface altitudes and and made it match the model grid - grid-wise. Next, use GIS magic to get the sinks (closed topographic) areas out of the DEM. Use more GIS magic to create flowlines from the DEM. We didn't have any luck with the National Hydrography Dataset - the flowlines don't match the topography and you get some arcs with the downstream ends higher than the upstream ends. When all of the GIS work was done (it's fairly high-level work) we had a DEM and flowlines that world match and work in GMS and were able to get functioning SFR2 packages. There are several advantages to the SFR2 package over the Drain or River packages - the primary one being the removal of the "infinite" term in the equation that lets the Drain and River packages take or add as much water as the head differences and conductivity allows. The SFR2 budget is limited to the groundwater that has been discharged to the stream and any surface water volumes that are directly applied.
  28. SFR Package - Arc interpolation control

    Okay - I see what you are saying. While there is no actual interpolation which applies a stream bottom elevation to a cell, there is an "internal" SFR2 interpolation which sets the stream bottom in the cell for use during calculations (as evidenced by errors which show up in the output file when a stream bottom elevation is below the bottom of a cell...and by the calculated depth of water in a reach [cell] in the istcb2 file). I might still consider putting this in the GMS development feature request if I have time in the near future. Based on what you are saying, I would want Z elevations from the arc's nodes and/or vertices used to generate segment elevations, as that is the item which is painful to put into the dialog boxes (you can easily put in similar hydraulic properties for all of the arcs, but the elevations are all individual entries). I'll think about what might work best.....there may not be a big push to get that done. This is the first model I've worked on with a large number of streams. I'm sure that most modelers don't go this route too often. Thanks again!
