Bases: Base[PBD3DEntity]

The 3D elastic volumetric material class for PBD.

Parameters:

  • rho (float, optional) – The density of the elastic material (kg/m³). Default is 1000.0.

  • static_friction (float, optional) – Static friction coefficient. Default is 0.15.

  • kinetic_friction (float, optional) – Kinetic friction coefficient. Default is 0.15.

  • stretch_compliance (float, optional) – The stretch compliance (m/N). Default is 0.0.

  • bending_compliance (float, optional) – The bending compliance (rad/N). Default is 0.0.

  • volume_compliance (float, optional) – The volume compliance (m³/N). Default is 0.0.

  • stretch_relaxation (float, optional) – The stretch relaxation. Default is 0.1.

  • bending_relaxation (float, optional) – The bending relaxation. Default is 0.1.

  • volume_relaxation (float, optional) – The volume relaxation. Default is 0.1.
