Abaqus/Explicit memory usage
Mon, 2012-02-20 09:35 - Bunnu mobile
Hi all. I am running forming analysis on abaqus 6.10 on 64 bit platform with 8 gb of RAM. How can I give max memory usage for abaqus/explicit? There is a built in option for abaqus/implicit but for explicit there is no such option.
I want to allocate max amount of RAM for the analysis. Please help me with that.

memory parameter
You can specify this at the command line with the "memory" parameter.
For example: to use 6 GB of RAM
abaqus interactive job=jobname memory="6 gb"
alternatively,
abaqus interactive job=jobname memory="6144 mb"
I hope this helps! Explicit will report the amount of memory it needs right before it begins actually doing increments in the status file (*.sta). If you don't allow it enough RAM, I believe it will have to store some of that information in scratch on the hard disk.

Actually, after looking at this closer on a problem of my own, I discovered that the memory parameter doesn't actually get used by Explicit during the analysis portion, only the pre-processing. Explicit needs whatever amount it needs, and it won't run if it isn't available.
I think you can make sure your page file is large enough to handle the overflow of data, and then you would still be able to run.
Sorry for the mistake in my previous post!
