User:Jcreer/GMS:MODFLOW Model Wrapper

Example of the MODFLOW model wrapper

The MODLOW model wrapper dialog will appear when running MODFLOW. This model wrapper dialog displays information about the MODFLOW run. Information displayed includes the following:

• The file path to MODFLOW executable being used in the model run.
• The file path to where the solution files will be generated.
• The Error vs. Iteration graph.
• The command line display.

Error vs. Iteration

The Error vs. Iteration plot will show iterations of the MODFLOW run. The plot is hard wired to only show 25 iterations. The Error vs. Iteration is usually showing the maximum head change, but this can vary as follows:

• SAMG prints end_res - head residual
• PCG prints BIGH - max head change
• PCGN prints MXHCH - max head change
• SIP prints BIG - max head change
• SSOR prints BIG - max head change
• DE4 prints BIG - max head change
• GMG prints BIGH - max head change
• NWT prints Fheadsave - max head change
• SMS solver prints ABIGCH - max head change
