In my model, a part has a cylindrical shape. I want to get the stresses on the circular surface using cylindrical coordinate I have changed the coordinate system to cylindrical system. However, I am bit confused wheter to use Material or Spatial frame type. When spatial frame is selected, cylindrical system does not appear for the linear elastic material node. I am guessing it is due to the fact that there are few non cylindrical part in the geometry. So only option remains is to select Material frame type. Will this give me correct results? I really need the stresses in terms of cylindrical coordinates. i would be greatful if someone could explain.

For example, using material frame type
solid.Sl11 should give the stresses in radial direction (please correct me if I am wrong).

Hi,

You can find the answers to most of your questions in

www.comsol.com/community/forums/general/thread/34639

And yes: solid.Sl11 will then give the radial stresses.

Henrik
