Axisymmetric analysis for internal pressure and force

[SergeyZh]

HI
I've just install Elmer to try it out. And wonder if it is possible to make this simple 2D FEA of a pipe section under internal pressure and axial force at the same time.
Thanks

Ye it is possible.

Ye it is possible.

thanks for a reply. Is there any similar FEA done with a tutorial how to achieve it?

[kevinarden]

I do not know of one, can you post the cad geometry, internal pressure, and end load?

[kevinarden]

Here files for a case. Geometry made up, internal pressure 200E3, end load 10K. Picture is the gray is undeformed, the deformed model is colored with the stresses.

Thank you very much for the effort. I'll check it out

After running it I got an error:

Code: Select all

ERROR:: CheckLinearSolverOptions: MUMPS solver has not been installed.
STOP 1

Change Mumps to umfpack

Or you can switch to an iterative solver like this

Hi

Note that by convention the axis should be aligned with y-axis (coordinate 2) and radius with x-axis (coordinate 1).
