class JointFrictionR : public NewtonEulerR
- #include <JointFrictionR.hpp>
This class implements a friction on a DoF for any NewtonEulerJointR.
Public Functions
-
JointFrictionR(SP::NewtonEulerJointR joint, unsigned int axis)
Initialize a joint friction for a common case: a single axis with a single friction, either positive or negative.
For use with NewtonImpactNSL.
-
JointFrictionR(SP::NewtonEulerJointR joint, SP::UnsignedIntVector axes = SP::UnsignedIntVector())
Initialize a multidimensional joint friction, e.g.
the cone friction on a ball joint. For use with NewtonImpactFrictionNSL size 2 or 3.
-
virtual void computeh(double time, const BlockVector &q0, SiconosVector &y)
to compute the output y = h(t,q,z) of the Relation
- Parameters:
time – current time value
q – coordinates of the dynamical systems involved in the relation
y – the resulting vector
-
virtual void computeJachq(double time, Interaction &inter, SP::BlockVector q0)#
-
virtual unsigned int numberOfConstraints()#
-
inline unsigned int axis(unsigned int _index)
Return the joint axis number assigned to a friction axis.
-
inline SP::NewtonEulerJointR joint()
Return the joint assigned to this friction relation.
-
inline unsigned int numberOfAxes()
Return the number of joint axes indexed by this relation.
