We are currently working on introducing Python interface. Once we have a first version available, we will let you know.

@dreamer2368 & @dylan-copeland can you review this PR?

Unfortunately, matching velocity is much more difficult job than matching displacement because velocity field is one more derivative of displacement. It is analogous to the fact that it is more...

yeah, that is very high. One way of reducing velocity error is to introduce reduced basis for velocity field as well, which we do not do for this nonlinear elasticity...

Oh, I missed that. Maybe we are indeed using velocity basis for nonlinear elasticity examples. I think that @axla-io implemented both. Not sure which one is being run currently.

It would be nice to include regression test for this example.

Introduce wiki page about Merlin in libROM repo

@dreamer2368 do you approve this PR?

@dylan-copeland we need your review again on this PR.

These are good resources. You may want to check out S-OPT paper as well because S-OPT improves the current state-of-the-art hyper-reduction technique, i.e., DEIM. See this paper ( https://arxiv.org/abs/2203.16494 )
