Wrong stress distribution on a customized cross section

[Anonymous]

Hi all, 

I have created a customized cross section in Robot and I have applied the section to a beam. As you can see in one of the images the beam is loaded with an uniformely distributed load and it is simply supported on 3 points. 

The stress distribution in the cross section is not correct as you can see in one of the image. look at the diagram beside the cross section, it should be continuous insteed I have vlues just for a small portion of the total section. 

can someone help me?

Hi @Anonymous 

Hello

I have tried to create similar section and checked stress distribution.

It seems to be correct in my file

So I have two questions

Which Robot version you are using?

Could you share your file for verification?
