How to input C, D, E and F points of a L-section beam under bending?

L section beam is a non-symmetric cross section beam so it seems a bit uneasy task to insert the 4 points, viz. C, D, E and F points of the cantilever beam under bending from the free end. Can anyone help me out here?

    Instead of using a PBEAM property, you can easily use a PBEAML property, as it already have the most common standard sections, and automatically computes stress points 1 to 8 for you, as the attached document from PBEAML help of OptiStruct.

    Y and Z are the local section coordinates, as shown in the picture below.

    The stress values are computed for the local Y and Z axis going through the section Shear Center.

    Just like the image on the PBEAML documentation:

    If you define points C, D, E and F like this, you will get the same results as teh PBEAML

    Notice that PBEAML property already give you these points with no need of further definition.

    PBEAM (elements 1 to 10)

    PBEAML (elements 11 to 20)
