| What FLOW-3D Hydro CANNOT do | Workaround | |------------------------------|-------------| | Fracture propagation | Use 1-way coupling: pressure loads → external FEA | | Crack closure/sliding | Not possible; treat crack as rigid | | Poroelastic deformation | Use + compressibility, but no stress tensor |
Below is a for approaching “crack” phenomena in FLOW-3D Hydro. flow 3d hydro crack
If you expect crack widening with pressure: → Export pressure history to a structural solver (e.g., Abaqus) and iterate. | What FLOW-3D Hydro CANNOT do | Workaround
This is the most critical part of the story. Once the crack exists, the physics of fluid dynamics takes over. Once the crack exists, the physics of fluid
The nightmare scenario for any engineer is that this process remains invisible until it is too late. The dam looks solid from the outside, but inside, it is hollowing out.
