FastCorotatedFEM is a minimalistic implementation of the corotated FEM method which was proposed in paper "Fast Corotated FEM using Operator Splitting" by Kugelstadt et al.
Hello! First of all - thank you for your work, it's an excellent real-time FEM simulation. There is only one thing I want to ask about and it is about collision response. In your 2D FEM implementation you use fairly simple direct clamping of particle position, however, when I tried this approach for this simulation it seem to cause a lot of artifacts. So the question is, how to implement proper collision response? Maybe you can point me to some parts of PBD code that do something similuar?
