5. Introduction to GW model GUI - What is the PMWIN ?
a pre-/post-processing of GW simulation systems supported various GW models (i.e., MODFLOW, MT3D, MT3DMS, PMPATH, PEST2000, UCODE, …)
Pre-processing
Prepare/Converse/Create MODFLOW input data visual. –> numerical method
Post-processing
Analyze/Coverse/Present output to Graphics and other attached models, like PMPATH and MT3D etc.
numerical method –> Visual.
