Hello, I would like a description of what the options for NRA are in the QUAD element. In the SOFIMSHA manual I found this.
However, the default option is 7 and when I export the database with the ROTATIONAL stiffness deactivated (which I configured using SOFiPLUS), then the NRA changes to 3. That is an option that I haven’t found in the manuals.
So the question: is there any other parameters for the NRA parameter (5, 6, … ??) and what those parameters mean?
