Coordinate Transformation

[abaqus-user]

Hello, everyone,
i am currently in a project where i have to bring a 3D surface (body with very small thickness) with a certain pattern into a tubular structure. All my attempts have failed.The point is to rotate the created surface around a coordinate axis to get the cylindrical structure. It is important that the structure of the surface is preserved. My basic idea was to transform the mesh of the meshed surface.
Thanks in advance for the help.

If I wrote in the wrong forum, please move this post.

There is an Abaqus plug-in named Wrap Mesh. You can download it from Dassault Systemes Knowledge Base. It should let you achieve expected result, if I understand your problem correctly.

That should work. Thanks for the answer. The Problem is, that "This operation connot be applied to a part that contains geometry". I need an orphan mesh, right? But how can I convert a 3D Solid or a 2D Shell to a working mesh?
Thanks in advance for the help.

Yes, you will have to convert your part to orphan mesh. You can do this in the Mesh module (Create Mesh Part option).

After doing this, I wanted to wrap the mesh but I still get this Error. I'm working with the PDE.

I have now an orphan mesh and a 3D space to wrap my mesh. If I try to do that, the same error occures. Can you help me?
As alternative I tried to transform the coordinates like this:

for coord in mdb.models['Model-1'].parts['Part-1-mesh-1'].nodes:
x = coord.coordinates[0])
y = sin(coord.coordinates[1])
z = cos(coord.coordinates[1])

My net becomes round, but it does not keep the structure I created in the planar.
