I would be very thankful if someone could help me with the command to set an initial velocity in FixedConstraint. I want to specify the same velocity for all nodes, is there an equivalent of fixAll for fixed initial velocity?
Hey @vanisri
The FixedConstraint aims at fixing a point by projecting a zero delta of velocity between two time steps:
Therefore, if you specify an initial velocity in your MechanicalObject, like:<MechanicalObject template="Rigid3d" name="myParticle" position="0 0 0 0 0 0 1" velocity="1 0 0 0 0 0" showObject="1" />Even if the DOF are fixed, a constant velocity will be kept.
Is this what you aim at doing?Best wishes,
Hugo
