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...
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...
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...
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...
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...
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?
"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...
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...
