RestShapeSpringsForceField

Context: Sofa.Component.SolidMechanics.Spring

Elastic springs generating forces on degrees of freedom between their current and rest shape position

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

  • points : points controlled by the rest shape springs

  • stiffness : stiffness values between the actual position and the rest shape position

  • angularStiffness : angularStiffness assigned when controlling the rotation of the points

  • pivot_points : global pivot points used when translations instead of the rigid mass centers

  • external_points : points from the external Mechancial State that define the rest shape springs

  • recompute_indices : Recompute indices (should be false for BBOX)

  • drawSpring : draw Spring

  • springColor : spring color. (default=[0.0,1.0,0.0,1.0])

  • activeDirections : Directions in which the spring is active (default=[1,1,1])

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

  • external_rest_shape : rest_shape can be defined by the position of an external Mechanical State

  • topology : Link to be set to the topology container in the component graph
