Common Mistakes to Avoid
Several recurring pitfalls show up when the selected tool does not align with simulation scope, network type, or the team’s modeling workflow requirements.
Choosing high-fidelity CFD when hydraulics workflow speed is the priority
OpenFOAM demands substantial setup effort for geometry, meshes, and boundary conditions and it can take time to debug solver stability and numerical settings. PIPE-FLO and PUMP-FLO provide faster iterative engineering workflows for steady network checks and pump and piping scenario comparisons.
