Hello , Does GID allow creating a reservor and interaction soil to water ?
GiD is a general pre/postprocessor. GiD itself doesn’t has any simulation code.
Simulations are done by problemtypes: https://www.gidhome.com/gid-plus/modules
There are different numerical approaches to simulate it (FEM, particle based, …)
Some video examples:
In GiD we are not experts on each problemtype.
You must conctact with each specific problemtype developer,
e.g. Kratos: GitHub - KratosMultiphysics/Kratos: Kratos Multiphysics (A.K.A Kratos) is a framework for building parallel multi-disciplinary simulation software. Modularity, extensibility and HPC are the main objectives. Kratos has BSD license and is written in C++ with extensive Python interface.
