Transient Thermal-stress analysis

[rsprsprsp]

Hello,

Can anybody help with issue of transient thermal stress? I managed to make thermal transient analysis, change et and get some structural results using thermal results. But i've obtained only static solution (as i read in help - ansys takes only first or last result from thermal transient file) so i have displacement at...the end of analysis i think...
So - how to force ansys to make nice animation about how my object changes it's shape during cooling?

I can think of 2 methods:
1. use direct coupled field elements and you can post-process the animation as required
2. for each time step that you have done a (sequential) thermal-stress analysis run, export out a plot in the same orientation and scale. Then, use a graphics program to create an animation from the plot files. Of course, you may also do this using the .grph files from ANSYS with some APDL scripting

thank, direct coupled element helped a lot.
but according to the se2nd option - is there possibility to import thermal temperature result file entirely (lets say my 100 substeps) or i have to solve problem 100 times, reading .rth file with different substep?

thank

Yes, if you use the 2nd method, you will have to solve the thermal-stress portion sequentially and for all the substeps that you want to extract a plot of the displacement. This is best done with an APDL script and a *DO loop.
