NX Nastran Contact analysis
Hi Andrew, Did you use previously shell elements? Are you sure you properly defined offset values? The contact doesn't work if the offset values are wrong. You have to also carefully define the maximum search distace of the contact. If that value is smaller than the distance between the contact... -
NX Nastran Contact analysis
I recommemd that you should try to solve this problem using linear static solver (SOL101) without any contacts. Or make an eigenvalue analysis. If the analysis works fine, then try to solve this nonlinear with contacts. SOL106 doesn't have surface contact capability so you can forget it. It... -
NX Nastran Contact analysis
Andrew, I've been using NX + contacts a lot. NX has very good contact algorithms. SOL101 has the algorithm from Ideas and SOL601 has the algorithm from Adina. Both of those work well. Have you built the model with shell or solid elements? Have you connected those parts to each other using... -
Unable to recover NX Nastran result file
Hi adnanh, NX has a poor memory management and this is the reason why you are not able to run big models with your desktop computer. It's interesting to see how 64 bit version works. You can try to control the memory management by vary the 'memory' value in NAST70 file. The default is... -
Unable to recover NX Nastran result file
Hi, Have you built up the analysis set properly? I especially mean Nastran Output Requests. (Model -> Analysis) -
Unable to recover NX Nastran result file
Is there F06 or OP2 files at all? Those are result files of NX. Have you tried to analyze a simple cantilever beam case (modeled using beam elements)? -
Question about Gap Elements
I don't exactly know how linear gaps works, but I think the linear gap works as the same way as the linear contact when SOL101 is used. The funcion is nonlinear although it is "hidden" (I mean you are not able to define gap parameters and nonlinear parameters). If I have understood correctly... -
Surface has no facets
Did you make the shell element mesh by extrtuding the curve? Or did you make at first the surface (geometry) by extruding the curve and then meshed the surface? -
Features of NX Nastran compared to NEi Nastran
"I tested both NX and NE a couple of years ago..." -> Was there the nonlinearity function from IDEAS inside the linear static solver (SOL101) when you tested NX? "There are things you can run in NE that are difficult or impossible in the others and vise versa." That's right! For example, NE... -
Features of NX Nastran compared to NEi Nastran
I'm sure you get the most reliable costs directly from a dealer. I've been using both of those - NE and NX. My opinion is that NE is the better marketed product than NX. I'm not trying to say that NE is bad product, but please, do not make a decision on the basis of the internet site. I give...
