PEST operates by modifying the input files for MODFLOW and SUTRA. Those changes to the input files do not affect how the model is defined in ModelMuse. If you run the model again from ModelMuse, all the inputs will be the same as before parameter estimation was performed. However, ModelMuse provides ways of importing and visualizing the modified model inputs created by PEST. The methods vary depending on the type of model and the type of input.
If PEST parameters are used with a data set, a file for each layer of the data set in the model will be created in the "arrays" subdirectory of the working directory of the model. Data in the files can be imported into ModelMuse with the File|Import Gridded Data Files command.
For MODFLOW-2005 and related models, the entire model can be imported to a new ModelMuse project with the File|Import|MODFLOW-2005 or -NWT Model command. Then any part of the model can be visualized with the Data Visualization dialog box.
For MODFLOW 6 models, the entire model can be imported to a new ModelMuse project with the File|Import|MODFLOW 6 Model command. Then any part of the model can be visualized with the Data Visualization dialog box.
For MODFLOW 6 models, model feature values can be visualized using File|Import|MODFLOW 6 Feature.
For SUTRA model, model feature values can be visualized using File|Import|SUTRA Features. In addition, data from data sets 14B, 15B, and the SUTRA Initial Conditions file can be imported using File|Import|SUTRA Files. SUTRA also generates boundary condition output files that indicate how boundary conditions were applied in the model. Data from these can be imported by selecting File|Import|Model Results.
Model feature data sets imported from both MODFLOW 6 and SUTRA models will be classified under "Optional|Model Results|Model Features" in the “Data Visualization” dialog box.
