  1. I feel that it is not currently useful as it only works with 32-bit machines. As long as you can import/export GIS format in SMS, that is all you should need.
  2. One option is to run the model in Unsteady mode, but for a long enough period of time that it becomes stable. I find this works better than running in Steady as it goes a lot quicker. I also turn off mesh adaption as it slows everything down considerably and just make sure I have good mesh. I should also point out that one of the most important things for Steady models is having a really good initial water surface elevation. This generally means running the model with higher tolerances for a while until the water surface is not changing any more and use that as the initial condition for a
  3. The hotstart file could be the culprit. If you are willing to share the files I can take a look. To apply the multiple processor option, ERDC gives the following guidance. Basically you need to install the SDK and then in the dos command prompt type in: mpiexec –n “processors #” adh.exe “filename” the file name is the adh input file that is created in sms. Multiple Processor Execution:A 64 bit Windows multiple processor version of AdH is now available. To utilize this capability you must have the HPC Pack SDK from Microsoft installed on your machine. We are unable to entertain requests for m
  4. On a side note, you can also set up ADH to run with multiple processors which is what I recommend as it can help with run times.
  5. ADH is an advanced model that takes a lot of time to figure out what works and what does not work. I have found that ADH can take a long time to run and I mean a really long time, if it is not set up properly. In general I like to to scalar density paving to generate my mesh and then modify it as needed (adjust nodes/elements to get rid of bad elements and refine if I need more). I also try to limit the number of elements and make them as big as possible as the automatic time step option for ADH does not always help and sometimes you just need to use a constant time step. I have also found
  6. In version SMS 11.1 the ns card now includes a nodestring id value after the negative value (see link below) http://www.xmswiki.com/xms/SMS:What%27s_New_in_SMS_11.1
  7. Are there spaces or special characters in the project name?
  8. There should be a *.sup file that you read into SMS which will read in the *2dm file (mesh) and all of the *dat files (results). If you can not find the *.sup file, you can read in the mesh then the result files manually.
  9. There is no easy way to back track and start over without using the map module to generate the mesh in the first place. In your case you could either delete the elements manually from the mesh or convert the mesh to map and make adjustments from there and then regenerate the mesh. Depending on the amount of elements in your model, the second option could take a long time to convert to map and then back to mesh. Cameron
  10. There is a newer version of SRH2D that writes out to the xmdf format which can be read into SMS. Aquaveo or the SRH2D developer has a copy of the newer version.
  11. Heimo, Would please explain how to the files in the TsPoint.zip you posted above? Thanks, Cameron Jenkins
  12. If I am going to model piers, I generate the mesh around the piers so that the elements start out small next to the piers and get bigger as they get farther away.
  13. The older versions of SMS can not handle newer CAD files. I would save the file as an older CAD, a GIS shape file, or create an geo-referenced image of the bridge pier data you want to see. Cheers, Cameron
  14. You would need to specify a nodestring for each boundary, in your case you would have three of them. The run would have to be dynamic to account for the change in flow out of the model.

    Undo Tool

    There is no undo tool in SMS. The best advice I can give you is to save often and save as a different name every time you are going to make a big change to your model. Cheers, Cameron Jenkins
