About FEFLOW
FEFLOW is the commercial heavyweight for finite-element subsurface simulation: fully unstructured 3D meshes that follow geology, variably saturated flow, density-dependent problems (saltwater intrusion, geothermal), heat transport and chemical reactions, with a modern interface and Python scripting (ifm/API).
It shines precisely where structured-grid MODFLOW gets awkward — complex geometry, open-pit and underground mine dewatering, coastal intrusion, geothermal fields. Licence costs are significant, making the MODFLOW 6 unstructured-grid capabilities the budget alternative worth checking first.
