Hi,
I'm using Femap as a preprocessor for Nastran solver. I want to reduce a portion of my model to a superelement and then use it in a subsequent analysis.
I'm using these options for Craigh-Bampton reduction:
This outputs a .pch file. I don't have a superelement license but from the official tutorial I've found out that for using DMIG matrices it is not needed. So I'm importing the SE through these commands:
But if I run the analysis I get the following errors and warnings:
They mention that q-set nodes are connected to elements, which should not be the case as they are created only during the SE creation and I don't attach any elements to them.
If I don't include q-set (=static reduction) the SE loads fine.
Does anybody know what I'm doing wrong?
