We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Yira,

You can use Static Structural for the Gasket analysis.

The pressure-displacement curve of a gasket often starts with a low stiffness, making solver’s guess quite far from the final solution, and causing a number of iterations. But for gaskets, often a good approximation to the final displacement solution is known. So a few tricks may work to accelerate convergence by allowing the solver to start from a good first guess, or by forcing the analysis to follow certain displacement constraints during the iteration.

Check the below link for the guidelines in case you face convergence isues.
