Common Mistakes to Avoid
Common buying mistakes come from choosing the wrong physics depth, underestimating model preparation effort, or selecting tooling that does not match your iteration and automation habits.
Selecting a linear-first solver for highly nonlinear contact problems
MSC Nastran is strongest in validated linear modal, buckling, and static workflows using SOL 103 and is not its primary strength for contact-heavy nonlinear use cases. For nonlinear contact and large deformation, choose ANSYS Mechanical or Simcenter 3D instead.
Ignoring solver workflow differences between impact-driven and quasi-static behavior
Abaqus provides Abaqus/Explicit for transient impact and highly nonlinear contact with stable time integration, while Abaqus/Standard targets implicit workflows. Choosing the wrong Abaqus solver pathway can lead to workflow friction even when the physics model is correct.
Overcommitting to a GUI-first workflow without planning for automation and repeatability
COMSOL Multiphysics supports scripting and APIs and organizes multiphysics studies through Model Builder, which helps repeatable coupled-physics setups. Abaqus also supports robust Python automation for repeatable runs, while CalculiX and Elmer FEM rely on text-based input management that demands workflow discipline.
Picking a multiphysics platform when your goal is structured CAD-based iteration cycles
SolidWorks Simulation is designed for direct SolidWorks model-based simulation studies with automated meshing and boundary condition tools that support fast iteration on CAD geometry. If you need nonlinear depth and advanced solver workflow control beyond CAD-embedded usage, choose ANSYS Mechanical, Simcenter 3D, or Abaqus instead.
