Dear all,
I want to cite the principal stress and principle direction in my permeability model for a porous media. But I cannot find such variables in the equation view. So how can i cite these two variables in my model?
Thank you for your help and time

Hi,
If you add a principal stress plot, you will see the names of the principal stress variables. The orientations have names like 'solid.sp1x'. ('1' for first principal stress, 'x' for x component).
These variables are not visible in Equation View since they are not computed by an explicit expression, but by solving an eigenvalue problem.

Henrik

hi
I have some question about principal stress.
if principal stress has negative value, and orientation has negative value such solid.sp1=-1 and solid.sp1x=-0.5
in this case, i want to calculate the principal stress of x component.
if I just multiply two variable, the value is 0.5.
is this value mean correct value of principal stress of x component?
