Hello Marco,

Just because the data entry dialog boxes use x,y,z even when you change to a Cylindrical Csys, you have to do the translation that x=R, y=Theta and z=Z. The cylindrical Csys is working like a “normal” cylindrical Csys. For example, here is a cylindrical solid with a pressure load on the side and there is a cylindrical Csys defined on the top. Notice that the Csys “triad” looks very different than a cartesian Csys.

Below is the Directional Deformation for the X axis using the cylindrical Csys. Since x=R, we see a circular pattern of deformation.

Below is the Directional Deformation for the X axis in the cartesian Csys. Note that it is not symmetric.

If I export the data for just the top edge using the two coordinate systems, I get the expected results.

Please explain why the cylindrical Csys is not working the way you expect it to.
