Hello to all,

I am trying to use ICEM CFD to generate a proper mesh for structural analysis.
After completing the meshing part, I have used output option to generate an input file for Ansys Structural.

Now I have a .in file but I don't know how to import it to Ansys Structural.
I have searched a lot but I am not able to find a way to read this input file into Ansys Structural.

Any help would be really appreciated.

Best wishes

any help?

Dear Daniel,

You can use the FE modeler inside the WB to transfer your .uns mesh file to a mechanical model that you can link to Ansys Structural. Here is an image:

Thanks for the answer.
I have tried to follow your suggestion, but I get the following warning:

"The creation of the Initial Geometry in FEModeler was a partial success only. Please review the state of the Initial Geometry object in the FEModeler Editor"

When I open the FE modeler it shows "problematic face" under initial geometry.

Well it seems that the FE modeler could not create a proper geometry from the input mesh (coarse mesh, 3D geometry creation while the mesh is in 2D, ...).

Do you mind sharing your mesh, so I can have a look?

Of course, you can download the .uns file from the following link:

Well in this case FE modeler generated the geometry, there is only a small issue with the parameterization. It can be solved by splitting your inner arterial wall in two surfaces in order to help the parameterization process.

But if you dont need to perform a remeshing with Mechanical then you can just ignore this message cause your geometry / model was created correctly and can be used in the structural analysis.

Thanks, I just panicked when I saw the warning

By the way, do you know what type of boundary condition should I use for the outer wall of pipe? I mean, what type of boundary condition in Mechanical is equivalent of stress free condition?

[Gweher]

What exactly do you want to simulate? I guess you want to perform the influence of inner pressure on the vessel. Stress-free condition implies zero normal velocity and zero tangential stress so you need a free slip wall.

yes, you are right about that. I want to model the vessel wall and I need stress-free condition for the outer wall. So I should use free slip wall for the outer wall of the vessel?

thanks for your help.

Which solver output do I need to select in ICEM to save a mesh file for ansys structural?
