Hello, I am having troubles with extracting 1D strain from op2 files using compose.
I used the function ' readvectorbuilder', when I choose 1D strain from the panel, I couldn't select any CROD element that I have defined previously. (see the image below)

P.S: with H3D file it is possible to extract 1D strain of CROD
but i have to use the op2 file since it's nastran standard .
