  1. Amy, If the dataset is a vector dataset then you can split it into its components (direction and magnitude) by right clicking on the dataset and selecting "vectors to scalars..." option. You can then use the time series plot type in the plot wizard to plot the values for the new direction dataset. Chad
  2. Vera, RMA2 might not be the best model to use in this situation. Have you looked into the coastal circulation models supported by SMS? ADCIRC and CMS Flow are the two that come to mind. There are also some options to couple wave models like STWAVE or CMS Wave to model the interaction of waves and circulation.
  3. I do not know of a specific sediment tutorial for FESWMS but there are some resources out there to find out more about the options within SMS. You can also look at the FESWMS manual for even more details. Here are some links to our wiki page and other posts that might be of help. http://www.xmswiki.com/xms/SMS:FESWMS http://www.xmswiki.com/xms/SMS:FESWMS_Sediment_Control http://aquaveo.invisionzone.com/index.php?showtopic=332&hl= Chad
  4. Mr. Raiz Roland Robert, I can help you find a solution to your modeling problem. Please contact me at cballard@aquaveo.com to discuss details of your situation further. Best regards, Chad Ballard
  5. It looks like Rusty has responded to this question already in your previous post http://aquaveo.invisionzone.com/index.php?showtopic=856
  6. SMS reads values larger than 360 degrees however these values correspond to a value between 0 and 360 degrees (ie. 540 degrees = 180 degrees) so there is no need to enter in any values greater than 360. The degree is measured from the positive x-axis counterclockwise. This makes straight up 90 degrees (or 450 or 810, etc) You may check what units RMA2 is looking for by opening the .bc file and checking the BWC Card. The second value is the IWMX flag and as stated in the manual this value corresponds to the units: 0 = miles/hour 1 = meters/second I believe by default this value is set to 1 meaning the winds would be entered in m/s but can be changed to 0 for mph if desired. The .bc file generated by SMS can be opened in a text editor like notepad.
  7. You may save a model at anytime and I would recommend doing it often since there is not an "undo" button.
  8. Please feel free to contact us at Tech Support to get this issue resolved. I ran a test case and did not run into the same issue and would like to investigate the problem further. Please email us at support@aquaveo.com
  9. Most likley the problem is that SMS cannot find the LeProvost database. Check the Preferences under the edit menu. Under the File Locations tab there is a file location listing for the LeProvost Tidal database. Check and make sure that the database is at this location. If it is missing it can be downloaded here: http://sms.aquaveo.com/leprovost.zip
  10. SMS can only be run on your local machine and not sharing files over a server. If you wish to share files with others over a network you will have to copy the files to your local hard drive then run them and make any changes then replace them again on the server. The errors you are getting are because of this. SMS was not designed to be shared over a network with multiple users running the same files and you will run into errors like you have. The project files can be uploaded and shared over a network like any other file but when running SMS and its models be sure everything is copied to you local drive.
  11. No, the tutorial is incorrect and I apologize for the confusion. In order to read the project file (.sms) you will need a HDF file viewer. The project file used to be a text file but has since been upgraded to improve the performance of the software.
  12. Ian, You can experiment with the Copy to Clipboard scale factor in the General tab in the display options. The higher this factor the greater the resolution. We have found however that most machines get an error if you set this scale factor much higher than 3 or 4 but feel free to experiment and hopefully you can find something that works for your publication.

  13. Joel, Time Series data can by inputted manually with a ts1 file. The format for this file can be found in the BOUSS2D documentation in Appendix D. If you select the cell string and assign a Wave Maker BC, in the Options (BOUSS2D Wave Generator Properties) you may specify where this file is located. You may also synthesize using the options in this dialog. Regards, Chad Ballard
  14. Bruce, How many wells do you have in your model? Chad
  15. Is your model transient? Selecting this option could cause problems in transient models. See this site for a little more detail if this is the case http://xmswiki.com/wiki/GMS:Output_Control
  16. To drape images check the box next to the Texture Map Image in the Display Options of either the 2D Grid or the 3D Grid. This will then "drape" you image over the surface of your grid.
  17. Yohannes, GMS supports the Stream package (STR1) - (http://xmswiki.com/wiki/index.php5?title=GMS:MODFLOW_Packages_Supported_in_GMS) The SFR package (Streamflow Routing Package) is not support by GMS 6.5. This does not mean that you cannot use this package with MODFLOW, just that you would have to manually edit the MODFLOW files outside of the GMS interface to add this package. To use the stream package in GMS you can create a stream coverage in your conceptual model and then map over the arc the represents your stream. You can assign different properties to your arc by double clicking on the arc to bring up its attributes. Regards, Chad XMS Technical Support
  18. What I think might help you is the Select by Data Value tool. In the Scatter Module click on the Select Scatter Point tool. Then in the Edit menu there is a Select by Data Value... option. A dialog should pop up displaying a min and a max data value. After entering in the value SMS will select the values according to the parameters you set.

    ADH

    You are correct, at the moment the GMS development team is working on the development of the ADH interface but there are no final plans on if or when it will be released commercially.
  20. A stack overflow error usually refers to a memory issue. How large is your model? How much RAM does your computer have?

    10-m DEMs

    WMS automatically distinguishes between the different DEMs (10m and 30m). Just remember that everything will now take longer to run since your DEM is more refined. There also are some options that can be changed in the dialog the automatically pops up when you import a DEM (Units, Thinning Factor, Smoothing Options, Etc)
  22. With GMS there isn't necessarily a maximum number of scatter points that you can have. The size of you model really is limited to the RAM that you have on the computer running the model. If GMS gives you a memory allocation error this signifies that you are running out of RAM and it cannot perform the task assigned.
  23. There is information in the FEMWATER manual starting on page 64. You can find this manual at the following link: http://pubftp.ems-i.com/download/GMS/GMS%2...ls/Femwater.pdf
  24. It seems like it should be alright but keep in mind that there are quite a few things that could cause memory problems. The way the memory is allocated creates certain restrictions, but a lot has to do with your model. A basic MODFLOW model might run fine with that many nodes but if you then add a number of observation wells then it might run out of memory.
  25. Yes, there is a size limit to how many characters (8) you can name your points, arcs, and polygons. I believe this is due to a limitation with the shapefile format (storing attributes in a table). I think you can create an alias and this might solve the name problem but I have never done this.
