Common Mistakes to Avoid

Missteps cluster around boundary-condition definition, model preparation discipline, and choosing a tool whose workflow strength does not match the team’s iteration pattern.

  • Using nonlinear contact without disciplined boundary-condition setup

    ANSYS Mechanical and Altair HyperWorks both require careful setup of boundary conditions to avoid misleading results when contact and nonlinear effects dominate. MSC Nastran also increases model setup complexity in advanced nonlinear and contact cases, which makes solver tuning and FE modeling discipline critical.

  • Picking a multiphysics workflow that does not match the team’s study automation needs

    Siemens Simcenter STAR-CCM+ can deliver repeatable parameter sweeps through STAR-CCM+ macros and Java customization, but overly customized graphical setup can slow work for highly customized workflows. COMSOL Multiphysics can require careful setup for tightly coupled systems and may demand scripting for the most advanced automation paths.

  • Ignoring meshing and pre-processing time for large assemblies

    ANSYS Mechanical and Altair HyperWorks can take time on large assemblies, and nonlinear or contact-heavy cases demand compute and solver tuning beyond initial meshing. Autodesk Fusion 360 Simulation and PTC Creo Simulate reduce geometry rework by tying studies to named selections or Creo model updates, but large assemblies still impact setup speed and solve turnaround.

  • Assuming open or command-line workflows will be GUI-simple

    OpenFOAM requires manual configuration of mesh, dictionaries, and solver settings, and GUI-based workflow coverage is limited compared with commercial CFD suites. CalculiX relies on external tools like Gmsh for meshing and ParaView for visualization, so preprocessing and workflow assembly must be planned explicitly.
