Hello Lovisa,
You sent me this link to an excellent tutorial on O-rings and fluid pressure.
You are using the APDL commands to add fluid penetration pressure as described in that tutorial.
In Workbench, using the Contact Tool, I plot Fluid Pressure as you have done.
The tutorial shows which edge to apply the pressure to and where to define the start_pt.
Best regards, Peter
