Stress plot on spherical coordinate system in Ansys Workbench

  Is it possible for us to define a spherical coordinate system in Ansys Workbench (I am using Version 19.0) like the first figure, and then plot the stress sigma_{thetatheta} as shown in the second figure? And How? Thanks very much.

  Workbench mechanical does not support spherical coordinate systems at the moment.
  
  you can either :
  
  use APDL commands (CS command to create the spherical coordinate System, use the RSYS and /SHOW commands to plot the result your want)
  
  use ACT capabilities to transfer the results from the global coordinate system to the spherical one. However, you will need to create the transformation matrix (there is no function to automatically do it even in ACT)

  Thank Aniket very much for your suggestions. One issue is that Ansys WB only offers the following stress plots but not the whole stress tensor with 9 components. Therefore, how can I get the stress sigma_{theta theta} along the polar direction as shown in my last post? In other words, how can I define the proper transformation matrix even with ACT?
