Description
Improved Levelset with Barrier method; original method via Zhao et al. (2023).

TODO

  • 2D benchmark tests for elastic sliding block on plane.
  • 3D benchmark tests for elastic sliding block on plane.
  • Benchmark tests for elastic rolling/sliding cylinder/sphere on plane.
  • 2D benchmark tests for Mohr-Coulomb sand flume.
  • 3D benchmark tests for Mohr-Coulomb sand flume.
  • Adhesion functionality.
  • "Uphill prevention" (potential versus actual tangent resistance).
  • Local PIC contact velocity.
  • Damping functionality.
  • Compatible with B-Bar.
  • OpenMP.
  • MPI.
  • Resume functionality.
  • Write tests.
  • Add documentation: update wiki, example input files/benchmarks.

Other Edits in PR

  • Mohr-Coulomb separate yield state.
  • Closed-form BSpline.
  • Refactor for updating mass and momentum within single loop & mutex, mitigating CPU idle time every step when using OpenMP. Previous separate update functions still available.
  • Geometry .vtk output off.

Potential Future Modifications

  • Separate levelset mesh implementation
  • Potential levelset normal source of error once mesh is separate
  • RBD levelset

Related Issues

  • Contact functionality
  • Nomenclature for subclasses/derived classes: want e.g. MeshLevelset, ParticleLevelset
