SV: Timesolver: Newmark method?

[Lars Rindorf]

Hi Matt

 

I could implement the Newmark method with your assistance. No problem. By it has to make sense for my work.

 

How fast and memory efficient is the petsc TS? Is it optimized in some way or implemented in some clever way numerically?

 

KR, Lars

We have not planned to do it, however if you would like to contribute it, we would help you do it. The
TS strcutures are fairly straightforward and looking at Crank-Nicholson should help.

  Thanks,
