Thermal analysis using beam elements

[GMarsh]

Hi,

I am doing a steady state thermal analysis in a model which has solid and beam elements (using Ansys Workbench 14). I get an error "Higher order elements are not valid for current analysis". But this problem is not there if I suppress the beam elements (even though the solid elements have midside nodes). Can anyone please suggest how to overcome this problem?

Thanks in advance.
Geoff

Apparently this is a bug in Ansys Workbench V14, which is corrected in V15. Workaround in V14 is to explicitly drop the midside nodes for beam / shell elements (for thermal analysis). Also for solid elements in the model, midside nodes should not be 'kept', but set to 'program controlled'.
