FEM and Strain based constraints in XPBD

[mjcg91]

Hi,

I would like to know if the FEM and strain based constraints could be updated simply by using XPBD style lambda update.I have read contracticting opinion whether C should be computed differently in PBD and XPBD or not.

Thank you

Yes, in principle this is possible. Just be aware that in this case you don't have a single compliance value but a compliance matrix.

So，have any plans add these constraints`s xpbd verson?

We implemented the FEM constraints for XPBD a few months ago. So check out the newest version.
