Hi all, I am m running an axisymmetric analysis and for some reason and there is radial deformation on the axis. I think the radial deformation at the axis should be zero, could someone please clarify what I might have done wrong? It is very close to zero, but not zero and i want to know the reason.

I import the temperature load as shown in the figure and obtain a result for deformation in X

Thanks

Check your geometry. Is the left edge exactly at X=0?

Hello, I drew this geometry in space claim, how do I check that ? Also is there a way to move the geometry ?

In SpaceClaim, create a YZ plane by clicking on the World X axis in the triad.
Use the Pull Tool to pull the edge on the centerline past the plane by a visible amount, then use the Split Body tool to split the surface using the plane and discard the extra you pulled over. Now you have an edge that is exactly on the Y axis.

Hi, Thanks i tried that. I still get a small deformation. The deformation is to the power of -5. But I still do not understand why there is a deformation, are there any other suggestions that I could try? or setting that I might have missed.

[peteroznewman]

I would just ignore a deformation that small.
If it bothers you, have you tried applying a displacement of X=0 on the nodes along the Y axis, leaving Y Free?

Thanks, It does not bother me, just wanted to know if I was doing something wrong in the setup. I will try applying the displacement in X=0 and update the result.
