v0.12.0

Modia3D v0.12.0

Diff since v0.11.2

• Support for variable-structure systems where variables (states) can appear and disappear during simulation
  • A simulation run is partitioned into phases that are called segments or modes (multi-mode modeling)
  • The transition between modes is triggered by a full restart
  • The number of modes is usually not known in advance
  • Modia3D is a built-in component for Modia
  • Using segmented simulation for Modia3D models defined in an action program, the following actions trigger a full restart for next mode (segment)
    • ActionAttach, ActionReleaseAndAttach, ActionRelease, ActionDelete
  • Enable modeling and simulation of 3D mechanical systems with dynamically changing degrees of freedom during simulation, see corresponding paper: DOI: 10.3390/electronics12030500
    • All applications and models mentioned in this paper, can be found in Modia3D release v0.12.0 or Modia release v0.10.0
• Add Force Elements WorldForce and WorldTorque for force/torque vector application by functions of time.
• Enable Force Element results by interface extension (element path and simulation model).
• Improve efficiency of FileMesh contact (faster support point calculation).
• Fix Animation Export:
  • Update three.js geometry type names, e.g. SphereBufferGeometry -> SphereGeometry.
  • Enable/fix FileMesh options useMaterialColor and doubleSided.
  • Disable double side rendering for standard objects.

Non-backwards compatible changes

• Requires Modia 0.10.0. Some internal interfaces have been changed
  (should not have an influence on user models).

Closed issues:

• Examples throw error, don't seem to import in Three.js (#119)
