Hello. I did it in the NX Nastran 11 using a simple 3 DOF model. Can somebody help me to understand this matrix output? How can write my 3x3 matrix from this data?
The NASTRAN Quick Reference Guide under DMI & DMIG has the full description of the DMI/DMIG form. You can write a program in your favorate programming language and convert the DMIGs into row/colum form. KAAX is stiffness, MAAX is mass, BAAX is damping, and I do not remember the VAAX.. You can check the NASTRAN DMAP Programmers Guide it may define it. All these books should be avaliable in the FEMAP help menu or in the directory as pdfs.
