Thank you very much for all your answers.
Our conclusion is:
ANSYS Elastic Curved Pipe elements (Pipe18) cannot capture bending originated by the pipe internal pressure.
Best regards.
Dear Drej,
Thank you very much for your answer. I am pretty sure this effect occurs (simple party blowers work on this principle)
Find attached two small "test bench" models: one with shell elements, the other one with pipe elements:

Dear all,
I am trying to model the bending due to the internal pressure on a curved pipe. When using Elastic Curved Pipe elements (Pipe18) with Elastic Straight Pipe (Pipe16) this effect does not appear... Is there any Real Constant or Keyoption which I should be using? My model is quite...
