Has any body noticed any performance problems when solving an FEA using NX Nastran 5.1 installed on Win 64bit.
It appears to me that it does not utilize the extra memory available with 64bit. I have run several tests and found that the more memory attributed to the solve under Solution Parameters make sthe simulation slower. Very unusual. The solve performance also seems to be very poor when you try to solve a medium size job i.e. 65000 elements with 1 contact region defined by surface to surface contact.
