Is this "crack fixed" issue related to a or a structural FSI failure simulation ?
For months, engineering forums and technical support tickets have been flooded with one recurring phrase: “FLOW-3D hydro crack fixed.” If you have ever run a high-velocity chute spillway model or a stepped dam overtopping simulation, you have likely encountered this issue. Suddenly, your perfectly continuous water jet splits apart mid-air, showing unphysical gaps (cracks) that look like shattered glass rather than flowing water.
To ensure your specific simulation model benefits from the crack fix, implement the following verification protocol:
When you import a CAD model into FLOW‑3D HYDRO, the software uses its method to mesh the geometry. If the original CAD surface contains gaps, inverted normals, or overlapping facets, the meshing process may produce incomplete surfaces, “missing” portions of the model, or leaks that allow fluid to escape where it should be contained.
If you are interested in trying this software, you can request a demo to see how these simulations are set up.
