TODO:

  • Implement trapezoidal rule
  • Implement BDF2
  • Implement Newmark
  • Test line search with trusted gradient
  • Test hyperelasticity
  • Test one iteration compared to EulerImplicitSolver ...
  • Design unit tests
  • Profile and perfs
  • Direct solving of bilateral constraints
  • Better convergence criteria (relative...)
  • Cleaning (decompose large functions ...)
