What exactly is an "out of memory error" in CST?

32 bit cst out of memory

I got that error from the electrostatic solver in EMS while using tetrahedral adaptive meshing. I'm hoping someone can explain what it means. Thanks.

Dear jpsmith123
maybe its a memory problem. look at task manager in performance during
of meshing the structure and see if it reach the limit of your memory.
or maybe you have a thin layers.

out of memory on line 572

Dear jpsmith123,

you have to consider that Windows XP (32 bit version) addresses only 2 GByte memory (RAM, or eventually RAM + HD swap) for single process. It is possible set a particular flag and, in this case, you have 3 GByte available.
Bye.

cst out of memory

Has anyone tried to investigate CST's performance on Win XP SP2 64 bit enviroinment? I am about to proceed into such an OS to see whether
it will be beneficial in terms of simulation time.

However, I was wondering: I now have 4GB or RAM (under 32bit WinXP).
Would my simulations become faster if I shift into a 64bit OS, when say, no
more than 2GB of RAM is needed to complete a particular simulation anyway?
In this case maybe 2GB of RAM under 64 bit won't offer any improvements
even if I leave behind a 32 bit system. Or perhaps I missed something...?

Cheers

The main reason to choose a 64 bit OS is related to the possibility to address a very big amount of memory, > 3 GByte. It's difficult to say if you have a meaningful improvement in the case of simulations with only 2 GByte memory or minus.
