Hi!
I would like to ask you about my problem. I think the problem is simple but dont know how to find the right solution.
I have a shell, which is fixed about 2 vertical lines.
I would like to use a transient analysis. In the first loadstep I would like to act with impulsive loading with a force in the middle of the shell. In the second loadstep I delete the force and let the plate vibrates freely. And here it is a problem. When I use Time-History Postpro I dont get free vibration but damped non periodic motion. I dont use damping in my case. I think the problem is in Displacement of LoadStep 1 as well.
When I use various deltime I get various displacement in postprocessing.
I enclose my script as well. Please help me.
Thanks
