Hello, I'm trying to create a flexible body file by using Craig-Bampton Method. I need to write nodal stress values into the .h3d result file. From the global output request menu, I choose the stress option with corner location, then an ordinary analysis that has standard loadstep (for example linear static case) is run, and i can obtain the corner values. whereas, for the flexibody generation case, the nodal stress values are not written in the h3d file. Is there any way to obtain corner stress values in a .h3d result file for a flexible body generation?
I have been working on Craig-Bampton method for normal mode analysis in which I aim to get a faster computational time result for 16 modes. Until now I unable to do so. I tried to use all the information obtained from the internet, but I failed miserably since I have no idea how to do it. I'm working with superelement . Just a simple structure. One superelement and one residual. With this, I attached my explanation of the structure I'm working with.
