apply prescribed pressure value

[jpereirasan]

Good morning STKO team.
I want to apply a value of 10 kPA Pressure on the ground surface nodes using the prescribedNodalValue command.
For this I create the condition and apply it on the geometry surface.
Then in the analysis steps part I activate it in the load pattern.
However in the post processor, the surface pressure values are still 0.
How can I fix this?
I am waiting for your answer.
Regards

Hi
Any updates on that issue?

You have to pay attention to this aspect.
If you want to apply the water pore pressure value, note that the water pore pressure is the velocity of the unknown

Dear STKO Team, thanks for your repply.
How i can do this if i'm working with SSPQuad UP elements?
Should i create a groundmotion object with a velocity timeseries with constant value equal to the pressure that i want to apply?
