Why are deleted loads reappearing in a multi-frame restart?
I solved 3 Loadsteps. After the second loadstep I deleted some boundary
conditions. I ran the third loadstep completely. Everything looks fine. Then
I do a restart at time 2.5 with the option 'endstep'. After that the deleted
loads are back and I see a different result for this step than before.
The multi-frame restart has trouble with deleted boundary
conditions. This is addressed in the 4th sample input listing of
the Basic Analysis Guide Section 3.10.2. It discusses
the need to reissue deleted boundary conditions.
