NX Nastran 5 with WinXP64bit
NX Nastran 5 with WinXP64bit
(OP)
Is NX5 and NX Nastran 5 really suited for Windows 64-bit operating systems?
IBM Intellistation Z Pro
2 x Xeon 3GHz Dual Core Processors
4GB Ram
Win XP 64 SP2
Every day I constantly battle with the performance of NX5 whilst using the Advanced Simulation module. In fact, I have a system crash every day where the computer just freezes. This normally happens after the computer has been runing for some time (several hours) and when I either attempt to save the .sim file or close all parts.
I dont use a space ball either. Using other FE software in the past, I have had much better performance. Not sure how efficient algorithms for contact solving are compared to other codes.

SUBJECT: Results from SMP runs in NX NASTRAN are incorrect
----------------------------------------------------------------------------
Affected Software: NX NASTRAN
Associated PR Number(s): 1645554
Scope: NX NASTRAN v5, v5.0.1, v5.1
Revision: 1.0
----------------------------------------------------------------------------
The results from all SMP solutions run on either Windows XP64 or LP64
versions of Linux result in incorrect results. This defect affects all
solution sequences of NX NASTRAN running v5.0, v5.0.1, and v5.1. It does
not affect results from runs on other platforms nor does it affect older
versions of NX NASTRAN.
At this point the only workarounds available involve avoidance: The user
may choose to run non SMP solutions (i.e. running with PARALLEL=1), to run
on a different platform/architecture, or the user can elect to downgrade to
a previous version. A fix will be available with the v6.0 release.

Have you contacted GTAC yet with these issues? If not, please do so as there is very little that can be done with only what you've written.

I did not submit an official IR just yet over my problems as I discussed things with a Siemens rep last week and decided to look into hardware set up first.
