Common Mistakes to Avoid
Common failures across these tools come from mismatched workflow expectations, insufficient CFD expertise, and geometry or coupling complexity that exceeds the team’s current setup capability.
Skipping geometry healing before committing to CFD runs
Large CFD failures often trace back to geometry and boundary issues that prevent watertight surfaces. Anys SpaceClaim addresses this with automatic face healing and defeaturing workflows designed for simulation-ready surfaces.
Underestimating CFD convergence effort for complex multiphysics cases
ANSYS Fluent and ANSYS CFX both require CFD expertise for stable convergence when models combine compressible turbulence, conjugate heat transfer, and moving meshes. Teams that avoid careful model selection and boundary conditioning often see unstable setups in CFX and Fluent.
Choosing an open-source CFD framework without planning for solver tuning and debugging
OpenFOAM and SU2 both rely on case-based runtime workflows and require expert tuning of mesh quality, numerical settings, and solver stability. Without dedicated CFD engineering time, validation effort becomes high and debugging becomes a major overhead.
Using a multiphysics platform for turbulence and near-wall effects without configuration discipline
COMSOL Multiphysics can require careful configuration for turbulence and near-wall effects, and large transient meshes can increase setup time. STAR-CCM+ also has a steep learning curve for solver settings and discretization control, which means teams must plan training and convergence checks.
