I am carrying out a transient structural analysis on a jointed mechanism. It is a reclining seat mechanism. Originally I applied the weight of the person as a distributed mass on the two brackets, but now I realise that a more realistic application of the weight is to use a remote force from the centre of mass. I was able to achieve convergence with my distributed mass but cannot with the remote force. Does anyone have any thoughts on this?
I have auto time stepping ON
Initial Timestep = 0.1 sec
Min Time step = 1e-2s
Max time step = 0.1 s
Solver Type is Program Controlled
