v0.5.1

Modia3D v0.5.1

Diff since v0.5.0

• Collision handling - MPR algorithm improved to enhance speed and robustness
  • collision pairing material
    • at initialization: a warning is given if a collision pairing material is not defined
  • improve support points computation of
    • FileMesh: use SVectors and better computation of support points
    • Capsule: a Capsule is already smooth therefore collisionSmoothingRadius is removed
  • MPR algorithm
    • Double64 from DoubleFloats.jl package is used for mpr algorithm to increase accuracy
    • amount of iteration steps is increased if more are needed for phase 2 and phase 3
    • if it's not possible to quit with the predefined mprTolerance the iteration quits with the best possible tolerance instead
    • collisions between ellipsoids and other shapes are treated like collisions between spheres and other shapes
  • store information like centroid in Object3D
  • remove some type instabilities
• FreeMotion joint
  • enable adaptive rotation sequence
  • add test model
• Enable ForceElements
  • add infrastructure
  • add Bushing and SpringDamperPtP
  • add test models and documentation
• Animation export (three.js JSON object scene)
  • fix initial orientation
  • enable visualization of bounding boxes (AABB)
  • enable Beam support
  • enable Capsule support
  • enable inner cylinder radius support (pipe)
  • enable CoordinateSystem support
  • enable Grid support
• Visualization with DLR Visualization Library
  • add visual shape kind ModelicaShape
  • remove some type instabilities
• improve testing
  • enable short and complete test runs
  • add planar motion test
• update documentation and installation guide
• clean up: remove unused code snippets
