Mapping from 2D to 3D in axisymmetric case with moving mesh

Hey,

I have results from a 2D axisymmetric model of a micro pump.To solve the problem I have used ALE and FSI. Now I need to map the results in 3D. I have actually done that using the initial mesh. Is it possible to do it on the moving mesh also? I have tried doing that but it shows the results at the reference mesh and nothing on the deformed mesh. Is there any way to do that?

Regards,
Amer

Hi

are you in 3.5 or v4 ?

Hey Ivar,

On my lab computer, I am using 3.5.
Although, I have v4 on my laptop but I haven't really gotten my hands dirty on it.

Hi

I'm not sure how to in 3.5 (any longer).
In >=4.1 it's a specific subnote (must admit I havent tried for ALE but why shouldnt it be ok ?)

Hey again,

This is what I get if I map on ALE mesh. Could it be because of resolution?

It doesn't plot where the mesh has deformed.

(I am attaching the image.)

Hi,

If I well understood your problem, you are trying to revolve your solution from 2D axial-symmetric to 3D. This is possible and quite easy. There is a step by step model in the doc.

However, I think that the ALE solution (motion of your mesh) cannot be revolved!! You need to get it in a full 3D model.


I hope it helps

Hi
Strange, unfortunately I do not have 3.5 with me ;) cannot say more

Hej,

Thanks for your replies!

Can anyone come up with an example in v4? (without ALE). I could try it and lets see if that would work with ALE too.
