I am trying to use CDAMP2 elements with a function based on time. The goal is to change the damping value at a point in time during the analysis. I am running an advanced transient non-linear solution. Function options in FEMAP only show frequency and displacement options. Any advice?
Also, I tried to create a second set of dampers as birth/death elements and thought it would provide additive damping, but instead they were ignored. Is there a limit on the number of coincident elements for two nodes? I was trying 3 springs and 6 dampers (1 of each in each direction).
