RegularGridSpringForceField

Context: Sofa.Component.SolidMechanics.Spring

Spring acting on the edges and faces of a regular grid

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

• stiffness : uniform stiffness for the all springs

• damping : uniform damping for the all springs

• showArrowSize : size of the axis

• drawMode : The way springs will be drawn:

• 0: Line

• 1:Cylinder

• 2: Arrow

• spring : pairs of indices, stiffness, damping, rest length

• springsIndices1 : List of indices in springs from the first mstate

• springsIndices2 : List of indices in springs from the second mstate

• indices1 : Indices of the source points on the first model

• indices2 : Indices of the fixed points on the second model

• lengths : List of lengths to create the springs. Must have the same than indices1 & indices2, or if only one element, it will be applied to all springs. If empty, 0 will be applied everywhere

• linesStiffness : Lines Stiffness

• linesDamping : Lines Damping

• quadsStiffness : Quads Stiffness

• quadsDamping : Quads Damping

• cubesStiffness : Cubes Stiffness

• cubesDamping : Cubes Damping

• 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
