Adding Multiple Grid Models

RockWorks | ModOps | Grid | Math | Add Multiple Grids

This program adds the node values in multiple existing grid models (.RwGrd files) whose names are listed in the current datasheet.

Example: Add together thickness values in four isopach grid files to determine total thickness of adjacent beds.

! In order for the program to match up corresponding nodes in the input grid files, they ALL must have the same dimensions (X and Y coordinates and range) and numbers of nodes. If you aren’t sure of the "size" of any grid file, use the Grid | Statistics | Report option to obtain a summary. See Resampling Grid Models if you need to re-dimension an .RwGrd file. See Grid & Grid Math if you need to perform other arithmetic operations on two grid models.

Step-by-Step Summary


  1. Open or create a datasheet in which the names of the existing grid models to be added together are listed. Here is a very simple example of how this datasheet might look:

  2. Select the ModOps | Grid | Math | Add Multiple Grids menu option.
  3. Enter the requested menu settings, described above.
  4. Click the Process button to continue.

    The program will read the input grid models in sequence, adding the node values together. It will store the resulting grid file in the project folder under the output file name you specified.

    The requested diagram(s) will be displayed in a RockPlot2D tab and/or RockPlot3D tab in the Options window.

  5. You can adjust any of the settings in the Options window and then click the Process button again to regenerate the diagram(s).
  6. View / save / manipulate / export / print the diagram in the RockPlot2D or RockPlot3D window.
