Underestimating nonlinear and contact tuning effort in structural multiphysics workflows
ANSYS Mechanical and Abaqus can both require iterative parameter adjustments to stabilize contact and convergence in complex nonlinear studies. Teams that ignore mesh quality controls and contact readiness often see slower convergence or higher compute time in ANSYS Mechanical and larger compute demands in Dassault Systèmes Abaqus for advanced nonlinear assemblies.
Assuming every multiphysics platform will be equally fast to set up for large coupled electronics models
COMSOL Multiphysics and Siemens Simcenter increase setup time for large coupled models because meshing and solver tuning must be handled carefully for stability. Siemens Simcenter’s higher configuration effort can slow early iterations compared with simpler workflows, especially when model interoperability depends on accurate data mapping.
Using OpenFOAM without CFD setup readiness or an external post-processing plan
OpenFOAM relies on solver-and-dictionary workflows that demand strong CFD knowledge and careful mesh quality management. Post-processing often needs external tools or scripting, so teams should plan for that integration instead of expecting a single point-and-click environment.

What are common causes of simulation errors or incorrect results across these tools, and how can users diagnose them quickly?
For SPICE tools like Cadence OrCAD PSpice and PSPICE from ti.com, incorrect stimulus setup or measurement selection often produces misleading waveforms, so automated probe windows and parameter sweeps help validate operating points. For full-wave solvers like Altair FEKO and COMSOL Multiphysics, insufficient meshing around conductive boundaries or geometry features can destabilize field solutions, so geometry-driven meshing and element quality checks reduce failures. For structural models in ANSYS Mechanical and Abaqus, contact definitions or large deformation settings can cause convergence issues, so preprocessing contact readiness and nonlinear solver setup usually resolves the underlying problem.
