Hello,
I m trying to simulate a model which involves two identical shell surfaces where their lower ends cannot move and a pressure is applied on them.
The positive pressure closes the gap between the shells and a contact occurs between them.
My probelm is that when i m trying to use varying pressure the model doesnt run while it is running for a pressure defined by 'ramp'. In any way both pressures are about the same magnitudes.
The mode of calculation is 'Static General'.
Thx a lot in advance
