New release for GeoTaichi 0.3.0

Bugs fix:

  • Fix the support domain of B-Spline MPM.
  • Fix bugs when simulating with MLSMPM.
  • Fix bugs when computing the intersection area of sphere and triangle.
  • Fix bugs when finding neighbors between MPM and patches.

New features:

  • A high-performance and memory saving Level-set DEM module and coupling with MPM.
  • Complex boundaries generated by the digital elevation model.
  • Flexibly generate level set particle from mathematical-based, geometry-based and polygon-based DEM model.
  • Add energy tracking functions, i.e., kinetic, gravitational, friction, damping, contact energy, for DEM particles.
  • Add hierarchical linked-cell method for polydisperse granular systems.
  • Add energy conserving model for irregular particles, the energy function includes linear model, hertz model and barrier and smooth friction model.
  • Add explicit single point two phase MPM module.
  • More advanced contact algorithm in MPM, including MPMContact, GeoContact, and DEMContact,
  • More advanced shape functions, including linear function, gradient smoothed linear functions, GIMP, quadratic and cubic B-Spline.
  • Two-dimensional and Axisymmetric MPM modules.
  • Add total lagrangian MPM modulus.
  • More stabilization techniques in MPM, including $\nabla \bar{v}$, APIC, TPIC and particle shifting method.
  • Add sparse data structure for background grid in MPM.
  • Automatically delete overlap MPM and DEM before simulation.
