ToolControl Panel

The control panel for the VM_to_EVS converter can be seen above. The first step in converting a project is to select a Visual MODFLOW project (*.VMG) with the Select Visual MODFLOW Project Folder and VMG File button. The converter will then locate all additional VMOD project files (as shown below). The user can also crop the extents of the project that has been read in by changing the values in the Starting Row/Column and Ending Row/Column fields.

The next step is to select the type of output that is desired. The first (and recommended) option is to create a set of EFF/TCF/DWR files. To use the MODPATH module the cell components Head, Hydraulic Conductivity, Effective Porosity, and Groundwater Flux must be selected as shown below.
