MeshMatrixMass

Context: Sofa.Component.Mass

Define a specific mass for each particle

Data:

  • name : object name

  • printLog : if true, emits extra messages at runtime.

  • tags : list of the subsets the objet belongs to

  • bbox : this object bounding box

  • componentState : The state of the component among (Dirty, Valid, Undefined, Loading, Invalid).

  • listening : if true, handle the events, otherwise ignore the events

  • isCompliance : Consider the component as a compliance, else as a stiffness

  • rayleighStiffness : Rayleigh damping - stiffness matrix coefficient

  • separateGravity : add separately gravity to velocity computation

  • rayleighMass : Rayleigh damping - mass matrix coefficient

  • massDensity : Specify real and strictly positive value(s) for the mass density.

If unspecified or wrongly set, the totalMass information is used.

  • totalMass : Specify the total mass resulting from all particles.

If unspecified or wrongly set, the default value is used: totalMass = 1.0

  • vertexMass : internal values of the particles masses on vertices, supporting topological changes

  • edgeMass : internal values of the particles masses on edges, supporting topological changes

  • computeMassOnRest : If true, the mass of every element is computed based on the rest position rather than the position

  • showGravityCenter : display the center of gravity of the system

  • showAxisSizeFactor : factor length of the axis displayed (only used for rigids)

  • lumping : boolean if you need to use a lumped mass matrix

  • printMass : boolean if you want to check the mass conservation

  • graph : Graph of the controlled potential

Links:

  • context : Graph Node containing this object (or BaseContext::getDefault() if no graph is used

  • slaves : Sub-objects used internally by this object

  • master : nullptr for regular objects, or master object for which this object is one sub-objects

  • mechanicalStates : List of mechanical states to which this component is associated

  • mstate : MechanicalState used by this component

  • topology : link to the topology container

  • geometryState : link to the MechanicalObject associated with the geometry
