Discontinous stresses after analysis

etrud011

Hello,

 

I have a double supported beam that I have divided into a non-design and design space. After running an optimization and generating the structure with ossremesh I did an FEA reanalysis on the model. When checking the stress contours I noticed that their were discontinuities between the design and non-design space. Running edge and face equivalence showed that there were no unconnected nodes. Both the design space and non-design space have the same material, but located in different properties.

What could be the problem?

 

Thank you,

Hi Eric

 

I think it depends on how the 'Simple Average' algorithm works.
By default, the averaging of components stops at component boundaries.

 

Try to set the switch at Contour->Average Options->Average across component boundary (Button below Averaging method).

 

If the structure is not connected by nodes (e.g. by contact only) it isn't possible.

 

Best Regards,

Mario
