template<class DataTypes >
void sofa::component::solidmechanics::spring::FastTriangularBendingSprings< DataTypes >::addDForce ( const core::MechanicalParams mparams,
DataVecDeriv df,
const DataVecDeriv dx 
)
overridevirtual

Internal addDForce Overloaded function, usually called from the generic addDForce version. This addDForce version directly gives access to df and dx vectors through its parameters.

Parameters
mparams
dfOutput vector to fill, result of $ kFactor K dx + bFactor B dx $
dxInput vector used to compute $ df = kFactor K dx + bFactor B dx $

Implements sofa::core::behavior::ForceField< _DataTypes >.

◆ addForce()

template<class DataTypes >
void sofa::component::solidmechanics::spring::FastTriangularBendingSprings< DataTypes >::addForce ( const core::MechanicalParams ,
DataVecDeriv f,
const DataVecCoord x,
const DataVecDeriv v 
)
overridevirtual

Given the current position and velocity states, update the current force vector by computing and adding the forces associated with this ForceField.

If the ForceField can be represented as a matrix, this method computes $ f += B v + K x $

This is the method that should be implemented by the component

Implements sofa::core::behavior::ForceField< _DataTypes >.

◆ addKToMatrix()

template<class DataTypes >
void sofa::component::solidmechanics::spring::FastTriangularBendingSprings< DataTypes >::addKToMatrix ( sofa::linearalgebra::BaseMatrix matrix,
SReal  kFact,
unsigned int offset 
)
overridevirtual

Internal addKToMatrix Overloaded function, usually called from the generic addKToMatrix version. This addKToMatrix version directly gives access to the matrix to fill, the stiffness factor and the offset used to identify where the force field must add its contributions in the matrix.

Parameters
matrixthe global stiffness matrix in which the force field adds its contribution. The matrix is global, i.e. different objects can add their contribution into the same large matrix. Each object adds its contribution to a different section of the matrix. That is why, an offset is used to identify where in the matrix the force field must start adding its contribution.
kFactstiffness factor that needs to be multiplied to each matrix entry.
offsetStarting index of the submatrix to fill in the global matrix.
