How to find the points on the beam with maximum and minimum bending stresses using simulation Xpress?

I designed a cantilever beam using part.

and I used fixture to fix the beam as a cantilever beam.

When I use the simulation xpress to obtain the results, I am getting the simulation results like displacements and von mis stresses.

What I want to find and verify with my calculated results is " the direction of neutral axis" and also "the points at which maximum and minimum bending stresses occur"".

Can anyone help me to do this?

Thank you
