Discrete Elastic Rods Based Simulations

Computational Science and Engineering Certificate Independent Research Project (Fall 2021).

This implementation adapted time-parallel frame in [Bergou et al., 2010] instead of space-parallel frame in [Bergou et al., 2008].

Update

May 23, 2023: Plan to polish this repo soon. I will evaluate the correctness of the implementation and add more tests. I will also add more comments to the code. I think there are something wrong with the stretching energy computation...
