Converting a 3D Dataset to a 2D Dataset

It sometimes happen where you have a fully developed 3D model in GMS and need to transfer a dataset from the 3D model to a 2D model. GMS provides a way to convert a dataset on a 3D grid to a 2D grid. From there the dataset can be exported as 2D data for use in a 2D model.

To acquire a 2D dataset from a 3D dataset, you need the following:

  • 3D grid
  • 2D grid
  • 3D dataset

To convert a 3D dataset to a 2D dataset, do the following:

  1. In the Project Explorer, select a dataset under a 3D Grid.
  2. Use the Grid menu to select the 3D Data → 2D Data command.
  3. Select option in the 3D Dataset → 2D Dataset dialog.
3D dataset to 2D dataset

The 3D Dataset → 2D Dataset dialog allows choosing which dataset to converted. By default, the dialog will use whichever 3D dataset is active in the Project Explorer. If another dataset is desired, from a MODFLOW simulation for example, you can make the change in the dialog..

The dialog also allows creating the new 2D dataset using one of the following parameters:

  • Maximum value in ij column
  • Minimum value in ij column
  • Average value in ij column
  • Sum of values in ij column
  • Highest active value in ij column
  • Value from k layer

K represents the layer number with 1 being the surface layer, and J and I representing the x and y locations of a cell (or column of cells) in the grid.

Keep in mind that one of the grids could be covering the other so if you want to observe specific data, you may need to turn off other data.

Additional additional information about converting 3D grids to other data can be found on our wiki.

Common Installation Issues with XMS

Are you having trouble installing GMS, SMS, or WMS? Here are three common installation issues, and how to overcome them.

Virtual Machines

The main issues when using virtual machines is selecting the correct type of installation. Single-user locks are not compatible with virtual environments. If you are trying to install XMS with a single-user lock and a virtual machine is detected, XMS will not install. You will need a network lock to get around this issue. Network locks are designed to be used with virtual machines. Single-user locks are not capable of being used as a network lock.

Firewalls and User Permissions

Sometimes, a good password will fail to install XMS, This is because your computer actually needs to contact our servers to verify the authenticity of the password. When an internet error comes up, it's typically related to a firewall, user permissions, or antivirus software blocking the connection to our servers.

Try one of these solutions to resolve this issue:

  • Whitelist which ever XMS program you are trying to install and the registration wizard.
  • Temporarily disable the firewall/antivirus software.

Note that firewalls are typically something each company's IT department handles.

If you are running Windows 8 or 10, and you are not running in a virtual environment, then the issue could be caused by a Windows feature called Hyper-V. Disabling Hyper-V can resolve the problem. You can find instructions on how to disable Hyper-V by reading this article.

Hardware locks

When installing a hardware lock, be sure to have your drivers installed and running before attempting to register the lock. Additionally, please also ensure that the lock is plugged into the computer at the time you are attempting to register. (Note that as a security measure, the reburn cannot take place remotely.) For instructions on how to install your specific type of hardware lock please visit our page here.

Feel free to contact our technical support team at support@aquaveo.com for more individual help in troubleshooting any of these problems. Please recognize that Aquaveo technical support can only help troubleshoot individual machine issues to a certain point.

How to Generate a Flood Depth Raster

After running your model, such as SRH-2D, you will have a water surface elevation (WSE) dataset. Did you know that, starting in SMS 13.0, you can use the WSE dataset to create a raster showing the flood depths?

SMS can create a flood depth raster by using the WSE solution dataset at a specific time step and comparing it to the initial elevation data. Using both of these datasets, it can then generate a raster that shows the flooded areas for a specific time step.

In order to create a flood depth raster your project will need a WSE solution dataset and an elevation raster. Once you have a raster:

  1. Select the desired time step for your WSE solution dataset.
  2. Right-click on the raster and select Convert To | Flood Depths.
  3. In the Select Geometry and Dataset dialog, select a geometry containing your WSE solution dataset. The selected geometry can be either a 2D mesh or a 2D scatter set.
  4. Next select the WSE solution dataset.
  5. Click OK to close the Select Geometry and Dataset dialog, which will launch the Save As dialog.
  6. Creating a name for your raster and click Save. (Note that the file should be saved as a "GeoTIFF Files (*.tif)".
  7. Hide the mesh and elevation raster to be able to view your new flood depth raster.

It should be noted that it may take a few minutes for the flood depth raster to be generated depending on the available processing power of your machine. Since a raster file is saved during the process, the file is available for use in other applications if desired. Coordinate data is saved with the file.

Now that you know to create flood depth rasters, try using them in your SRH-2D projects in SMS.
