NX Nastran topology optimization with SOL101
Hi, generally spoken, you are right. But SOL200 does not support topology optimization!!! That's why your answer is of no benefit at all. Kind regards -
NX Nastran topology optimization with SOL101
Hallo all, for the input file below I'll get the following error messages. I'd like to minimize mass (MASS) while the compliance(COMP) stays above 80% of the starting compliance. *** USER FATAL MESSAGE 5006 (APPEND) INPUT FILES HAVE DIFFERENT RECORD TYPES *** SYSTEM FATAL MESSAGE 3007... -
NX MSC Nastran Equivalence (TOPVAR & DRESP1)
Hello alltogether, I'm searching for the equivalence of TOPVAR and DRESP1 in NX Nastran. I have to use TOPVAR and DRESP1 in a NX Nastran SOL 200 simulation and I don't know how to figure it out. Can anyone give me a hint? Kind regards Fite -

SOL 200 - Problem with DRESP1 and TOPVAR
Hello, I'm trying to run a simple topology optimization with NX Nastran and SOL 200. I've put the input-file to the appendix (see link below). When I start calculating, I'll get the UFM 316 and 307: *** USER FATAL MESSAGE 316 (IFPDRV) ILLEGAL DATA ON BULK DATA ENTRY DRESP1 DRESP1 1... -
Membrane, bending and peak stresses from von Mises
Hello everyone, I’m using Patran 2013 and the MSC.Nastran solver. For a 3D pipe assembly, I calculated the von Mises stresses. Now I need to calculate the membrane, bending and peak stresses from the von Mises stresses and evaluate these stresses due to a given standard specification. In ANSYS...
