Re: explicit time stepping

[Konstantinos Poulios]

Dear Anne-Cecile,

I am personally not aware of explicit time-integration examples in GetFEM. Explicit time integration is basically simpler than implicit. Instead of doing 6-7 Newton steps until your equations converge, you add inertia and you just use the non-converged result from the 1st Newton step of the implicit scheme. You need much more explicit steps, to achieve the same accuracy as with the implicit scheme. Explicit time integration does not work well with contact either. Hence I would recommend you to look at other performance improvements, like maximizing the size of the time-steps.

Best regards

Kostas

Dear all

 

Do you have an example of switching from implicit time to explicit time stepping?

 

Thank you
