ANSYS V13 New Features: Thermal-Stress analysis
Normally when we run thermal-stress coupled analysis, we must have the same model in both thermal and stress analyses.
The same model means the same geometry, the same mesh, etc. In many cases the same model is unnecessary. For example, only parts of a model have thermal load or thermal analysis and stress analysis have different requirement on mesh to get precise results. In V13 there is no such limitation.
First set up a steady-state thermal or transient thermal analysis as usual. After solving, we get some results such temperature distribution:
Now go back to the project page and insert a separated static structural or transient structural analysis. Share the Engineering Data and Geometry cells if required and then drag the Solution cell of the thermal system onto the Setup cell of the structural system. In this example, we will use different geometry:
Now we open the Mechanical application for the structural analysis, we can see an Imported Body Temperature load is automatically added into the structural system's tree under an Imported Load folder. Select appropriate geometry in the Details view:
After define all settings, we can import thermal load:
The imported body temperature is slightly different from that of thermal analysis:
Thereafter there is no difference to applying other boundary conditions to the whole model and to solve the model as usual.
