Choose between bonded and no-separation contact for clamped interfaces, then verify with Contact Pressure and Contact Status.
Match bonded, no-separation, or frictional contact to each bracket joint, then verify with contact status and pressure plots.
Decide when to use Pure Penalty versus Augmented Lagrange contact in Ansys Mechanical for sliding assemblies, with configuration steps and convergence trade-offs.
Use Augmented Lagrange contact with stabilization to converge bolt preload in Ansys Mechanical, then verify with mesh refinement and hand calculation.
Learn how to use Ansys Mechanical submodeling to resolve local stress concentrations without the computational cost of a globally refined mesh.
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Deflection when rotations exceed roughly 5–10 degrees or displacements are large enough that the undeformed geometry no longer represents the structure accurately.
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.
Learn how to choose between Steady-State and Transient Thermal analysis in Ansys Mechanical based on thermal mass, load variability, and computational cost.
