template<class DataTypes >
void sofa::component::forcefield::SPHFluidForceField< DataTypes >::addDForce ( VecDeriv &  df,
const VecDeriv &  dx 
) [inline, virtual]

Compute the force derivative given a small displacement from the position and velocity used in the previous call to addForce().

The derivative should be directly derived from the computations done by addForce. Any forces neglected in addDForce will be integrated explicitly (i.e. using its value at the beginning of the timestep).

If the ForceField can be represented as a matrix, this method computes $ df += K dx $

This method must be implemented by the component, and is usually called by the generic ForceField::addDForce() method.

Deprecated:
to more efficiently accumulate contributions from all terms of the system equation, a new addDForce method allowing to pass two coefficients for the stiffness and damping terms should now be used.

void sofa::component::forcefield::SPHFluidForceField< DataTypes >::addForce ( VecDeriv &  f,

) [inline, virtual]

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 method must be implemented by the component, and is usually called by the generic ForceField::addForce() method.
