A technical guide to selecting contact formulations in Ansys Mechanical. Compare Bonded, Frictional, and Rough contacts to balance convergence speed with physical accuracy.
When modeling high‑deformation, high‑strain‑rate events like vehicle crashes, selecting the right solver is critical. This guide compares explicit and implicit solvers, explains trade‑offs, and walks through a practical implementation and validation workflow.
A diagnostic guide for resolving Newton-Raphson non-convergence in Ansys Mechanical, covering load stepping, contact instability, and material nonlinearity.
Learn how to use Ansys Mechanical submodeling to resolve local stress concentrations without the computational cost of a globally refined mesh.
Learn how to use Ansys Workbench's Design of Experiments and Response Surface methodology to minimize mass while keeping von Mises stress under yield.
Turn on Large Deflection when rotations exceed roughly 5–10 degrees or displacements are large enough that the undeformed geometry no longer represents the structure accurately.
Learn how to perform a mesh convergence study in Ansys Mechanical to ensure your FEA results are accurate and independent of element size, while avoiding stress singularities.
Nonlinear static with automatic contact in Ansys Mechanical speeds validation of latches and clips, but results depend on mesh density in contact zones and calibrated elastic-plastic curves.
Solver stops with Contact convergence failure or Maximum iterations reached. Use a short cause table, ordered checks, and targeted fixes to isolate penetration, stiffness mismatch, time stepping, and over-constraint issues in Ansys Mechanical.
