Importing highly complex, un-smoothed CAD or STL files for gates, turbines, or natural riverbeds can create problematic mesh interactions. If a solid surface cuts through a mesh cell at an extreme, razor-thin angle, the solver may struggle to calculate accurate area and volume fractions. How to Optimize Your Simulation Setup
If the cell size is larger than the thickness of a thin hydraulic wall, the FAVOR™ algorithm cannot resolve the solid geometry properly, creating a perceived "crack."

No software is perfect, and Flow-3D Hydro has its quirks:
For hydraulic and environmental engineers, software stability is just as important as the accuracy of the physics. Recent updates to have addressed critical technical hurdles, often referred to in technical circles as "cracks" or software bugs that previously hindered simulation performance. Importing highly complex, un-smoothed CAD or STL files
While the solver's ability to heal these issues is a powerful feature, frequent "crack fixed" messages indicate that your model is operating under high numerical stress. The most common engineering scenarios that trigger this mechanism include: 1. High-Velocity Impacts
If you are seeing errors, it is likely due to one of the following scenarios: How the Solver Fixes It No software is
A software update for FLOW-3D may not be compatible with an older, patched license file. Steps to Fix/Troubleshoot Licensing Issues
If your simulation runs fine initially but crashes a few hours in, you are likely running out of memory.
