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.

Hello Arnaud,

It is good that the error went away. The crashfront algorithm in *MAT_058 seemed to be causing the problem.

You should create a new thread for the new problem. This way, it will be easier for other users to find relevant information about a specific problem.

By the way, you are running explicit. Refer to the LS-DYNA user manual for the lctm parameter on *CONTROL_TIMESTEP. Also, Google "how to perform implicit simulation in ls-dyna?" and you should find the answer.

 

Reno.
