When I use a velocity constraint to force a particle not to move in a certain direction, there must be a 'reaction force' on the particle. I use KM.auxiliary_eqs to find reaction forces, which works very well in general!
However, if I try to find the reaction force due to a velocity constraint, it does no seem to work: The force term of the equations of motion contains the 'virtual speed', its time derivative and the reaction force. Am I doing something wrong, or do velocity_constraints and KM.auxiliary_eqs just not work together? I attach some code, showing my problem. *Any help is greatly appreciated!* -- You received this message because you are subscribed to the Google Groups "sympy" group.
