Reply To: How to apply displacement derivative dependent force on bunch of nodes in apdl?

I don't understand your loading description completely, but it's definitely not a standard one and would require a very complicated APDL script to accomplish.  If the analysis was divided into many small time steps, the current velocity vector of each node could be computed after each load step based on the current displacement increments divided by the time step.  Your function W(x,y,z) could probably also be evaluated at each time step and included in the force calculation.  This would require quite a lot of skill with Ansys APDL, but it's possible.
