Hello,

 I am simulating a pressurized PTFE membrane with an O-ring in ANSYS as shown below. A calculated force from the bolt is exerted on the O-ring to assume the clamping force from the bolt to the membrane. I am having issues with the properly constraining the O-ring and applying the force on it. Pressure is applied beneath the membrane.

O-rings are usually constrained in a annular pocket. I suggest you add the three surfaces of that pocket as rigid bodies to this simuation.
Also, If the geometry and loads are all axisymmetric, you will be much better off creating a 2D axisymmetric model.
Please reply with a 2D radial slice of the geometry for further discussion.

Hello Peter Thanks for your help! I changed to 2D radial slice and it worked.
