Defining stiffness and Damping as a function of time

Can we define stiffness and damping as a function of time?

Yes, it is possible to define stiffness/damping as a function of time in RBD. One can either write the Python script directly or use the variable load extension. Attached is a simple test case. It defines time-varying stiffness or damping using a Python table. Note that this model needs to be solved in meters.
