ANSYS WB - explicit - pressure/force load followed by displacement

[assafwei]

Hi,

I have a process I want to simulate using ANSYS explicit.
I am using WB for the modeling.
I need to apply on a bosy in the model a certain pressure/force for a short period of time, and then a displacement on the same body in the same direction for a short period of time.
The problem is that I cant start the displacement from time=0 because I need a short time where there is only pressure, but WB wouldnt allow this, I have to prescribe 0 displacement from the begining of the analysis which means that the part is constrained in this direction (0 movement) and then the pressure I prescribed is acting on a fixed body (0 displacement) which is not what happens in real life.

I hope I managed to explain myself...

Any ideas how I can model this?

Thanks.
