GeoFlow - 3D Geomechanical Simulator
GeoFlow is a fully coupled 3D geomechanical flow simulator.
The simulator utilizes modified Arnold-Brezzi finite elements (Arbogast and Chen, 1995) for the fluid pressure, standard finite elements for the displacements and finite volumes for phase transport. This combined with adaptive unstructured tetrahedral grids and a fully coupled approach to solving flow and mechanics delivers highly accurate numerical solutions for both the primary variables (fluid pressure and mechanical displacements) as well as derived quantities such as strains, stresses, fluid velocities, etc.
- Built from the ground up, provides a clean software solution
- Solves Biot’s equations of poromechanics using a monolithic discretization on the same grid for pore pressure and mechanical displacements
- Resolves flow and mechanical quantities at every spatial location and every time step
- Delivers optimal accuracy and robustness
- Eliminates guesswork from iterative linking of different mechanical and flow codes
Geological features, including faults are included as fully meshed geobodies. Global-local capability:
