Having studied a large number of bolted machine assemblies, I also fancy top-down substructuring in the 21th century. Below is a template for the recipe that I have used for some years. Through the creation of a "dummy solution", the recipe deals with shortcomings in ANSYS which may be absent in the most recent releases (feedback on that issue would be interesting). At the end of the procedure, load step numbers on "newtotal.rst" will be one higher than what applied for your superelements. This is due to the dummy solution at the beginning of the file.

To do that, I have had to expand results of the Super elements (say SE1.DB) as a seperate result file SE1.rst. I have more such super elements viz., SE2, SE3 and SE4. I am able to see the results in all these corresponding rst files. > Now, I would ideally like to see all these results in one file. Is that possible?
