CQC - Error
Hi all,
I am trying to implement the CQC from the responseSpectrum routine but smth is wrong and the results are too big in magnitude. I am trying to fogure out what I am doing wrong, any ideas will be appreciated.

Can you attach your Tcl files (Zipped) ?
Re: CQC - Error
Here's the modified file.
You were combining only the 3rd column.
Now I set up a script that combines all components.
Then it creates a Nx12 matrix (stored in a file) where N is the number of elements, with the CQC-combined forces.

Re: CQC - Error
It was just a round-off error before computing the square root.
It can happen when a mode is not excited in the requested direction.
Now I added a small check to handle this rare round-off errors
