Poor mans way of FEA with increased Virtual Memory.
(OP)
If time is not an issue, is there a way to get around the limits of winodws 4GB limit on virtual memory? I think there is. This link talks about increases virtual memory to 64GB.
Increasing virtual memory
However I did to do more research on the topic. What do all of you think?

RE: Poor mans way of FEA with increased Virtual Memory.
I recently had the dubious pleasure of running a large-ish model (for me) on my laptop
RAM
256 Mbytes - 2 days
784 MBytes - 4 hours
1.5 Gb - 30 minutes
Since I was doing a DOE with 80 iterations I was rather keen to spend the money on the RAM and get the solve time down.

1. 32-bit processors are limited to 4-Gbytes
2. the compiler might limit how much memory can access
3. Win-XP Professional has a limit of 4-Gbytes.
4. the application dynamic libraries might be compiled for 32-bit processor -- thus cannot go behond 4-Gbytes.
Any one of these limits will stop you from accessing more than 4-Gbytes of memory total.
You will need at least a 64-bit processor and the proper compilers, OS, and application to access more than 4-Gbytes.
