how to get the directions of principal stress
Altair Employeehello,everyone
I just want to know how could I get the direction or angle of principal stress, as it show in the tensor plot. I have been struggling with this problem since yesterday, but I didn't get anything.
Thank you for you time..so..much..
Any advice will be appreciated.

Thank you so much for you reply.
I am so sorry for I didn't express my question clearly.
As your screenshot shows, different element have principal stress with different direction. I just want to get the direction/angle in numerical. Then I can calculate something based on this direction. I don't know if I have right expressed what I want to get. I want to a direction in numerical, such as l=(0,0,1) which means the major principal stress direction of one element parallel with Z-axis. Then the l=(0,0,1) is what I want to get.

Altair EmployeeHi, @Q.Nguyen-Dai
I send the question to support@altair.com..They reply that hyperworks doesn't support to get this direction..
thank you so much..
Element tensor is presented in element's axis, I think. So if you can get this tensor, you can compute yourself the principal stresses and also their direction.
