Generating a Solid Model Statistics Report

RockWorks | Utilities | Solid | Statistics | Report

This program is used to get a general summary of the contents of an existing solid model file. The statistical summary is displayed as a textual report, in which the summary of node values and computed statistics are displayed in a document in a text editor.

You can use the statistical summary in a variety of ways: If you are performing mathematical operations with two solid model files, you can create a summary of each to assure that they have the same dimensions and numbers of nodes. If you are creating a solid model of geophysical or geochemical data using different modeling methods, you can create a summary of each model to view the differences in the range of the G-values.

Solid Model File: Click to the right to browse for the name of the existing solid model file (.RwMod) to be read and summarized.
Node Values = Percent: Insert a check here if the solid model selected above contains G values that represent percent, such as percent sand. If checked, the program will compute "Material Volume" and list this in the output report.
- For example, if the solid model contains G values that represent percent sand (ranging from 0 to 100) the program will calculate sand volume based on this equation:
  sand volume per voxel = voxel volume *(node_value/100)
  This will tell you total volume of sand which will likely be different from simple total model volume (unless all voxels represent 100 percent sand).
Conversion Factor: If your node values equal percent (the above setting is checked) and the values range from 0 to 100, the Conversion Factor should be set to "1". This tells the program to use the equation shown above for the material volume computation.
If, however, your node percentage values are entered as a different data range, you can enter a multiplier for the equation. For percentages entered as 0 to 1, for example, you would enter a Conversion Factor of 100.
sand volume per voxel = voxel volume * [(node_value/100) * 100 ]

Step-by-Step Summary

This tool does not require that any data be displayed in the Utilities datasheet. The only input file is the existing solid model.

Access the RockWorks Utilities program tab.
Select the Solid | Statistics | Report menu option.
Enter the requested menu settings, described above.
Click the Process button to continue.

The program will read the indicated solid model file and compute the general statistics. The statistical summary will be displayed in a text tab in the Options window.
From here you can print the information, copy it to the clipboard for pasting into another application, save the information on disk, etc.

Here's an example of a report:
