Memory Allocation - Nastran can't find it all.


My PC has 3Gb of ram as indicated by the XP system properties,
The NX Nastran .log file states there is only 2047Mb of physical memory available.
Can I force the amount of available memory in the .RCF file, or is there a 2Gb limit
for NX Nastran on XP ?

Hi!
I think the problem is that Win32 only can allocate 2Gb per process without the
/3GB switch. Maybe setting that switch will help. I haven't tried it myself but
I will.
Here's the link how to do it:
