How to replicate this in ansys?

How can I inflate a balloon/ pillow in ansys and find the stress on the surface?

Hey,

did you try to just model your geometry and apply pressure on the inner wall as a boundary condition?

As magnitude you can use tabular to simulate increasing pressure.

I created a hollow sphere of 1m. Imported the geometry and used symmetry tool in design modeler to make a quarter section of the sphere.

Then I used static analysis. I applied a pressure inside the hollow sphere. I meshed it and when I solve it I get an error message saying no support.

I have seen many tutorials where they are able to get a solution without adding any fixed supports or displacements. What should I do?

If I have to add a support or constraint, where should I add it.



Thankyou
