Thx for reading my post. Please see attached model. I would like to support the bottom surface og the footplate so that i can not move down in the -z direction but can only deflect upwards in the +z. This would mean that the footplate is only RESTRAINED for downwards deflection. This corresponds to the plate laying on a concrete block. How can add this kind of support?
Hope anyone can help

Very true and obvious 🙂 duuh!
A combination between a case (that stand alone gives incorrect results) with other cases provides correct results, that whas my concern; but you cleared it.
( I could be a little bit nosey and ask who/why does this happen, but I shouldn't go offtopic, so i'll ask this later)
THANKS AGAIN for your anwsers, very helpfull.
If you mean why lateral load case does not converge then check it may happen that just overturns the model (all UZ+ supports are switched off as the model starts to rotate). In other words check where your neutral axis is located vs. the support arrangement.
