PolynomialSpringsForceField

Context: Sofa.Component.SolidMechanics.Spring

Simple elastic springs applied to given 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

  • firstObjectPoints : points related to the first object

  • secondObjectPoints : points related to the second object

  • polynomialStiffness : coefficients for all spring polynomials

  • polynomialDegree : vector of values that show polynomials degrees

  • computeZeroLength : flag to compute initial length for springs

  • zeroLength : initial length for springs

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

  • compressible : Indicates if object compresses without reactio force

  • drawMode : The way springs will be drawn:

  • 0: Line

  • 1:Cylinder

  • 2: Arrow

  • showArrowSize : size of the axis

  • springColor : spring color

  • showIndicesScale : Scale for indices display. (default=0.02)

Links:

  • 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

  • object1 : First object associated to this component
