ABAQUS Data Storage Manager error

ABAQUS Data Storage Manager error

ABAQUS Data Storage Manager error

(OP)
Hi,

I have an explicit job that has run OK in the past, but now when I run it, it gets through the pre-processor OK, but when starting Explicit I get the following error messages:

***ERROR: ABAQUS Data Storage Manager error
***ERROR: blo_Access, Access Block
***ERROR: NoDyn, Unable to obtain sufficient dynamic memory
***ERROR: Use command "limit" to increase datasize or contact your system manag

Any ideas?

Thanks,

Charles Breen

RE: ABAQUS Data Storage Manager error

It looks like you have exhausted virtual memory (=actual physical memory + page file size). To check this start your run again and monitor memory usage via the windows task manager. On the performance tab, at the bottom is a box titled "commit charge" with figures for the current total memory being used, the limit available and the peak usage. If your total equals the limit value then obviously no more memory can be allocated, your job then fails and evidence of this is left in the peak figure value.

If this is the case then the page file size can be increased, BUT TAKE GREAT CARE ! Just merely upping the size will almost definitely result in a heavily fragmented page file, which the standard XP or 2K defragger will not resolve. There are various techniques to avoid this happening without using a boot time defraging tool (i.e. initially setting the size to zero, defragging and then setting a sufficiently large size or creating a new page file on a seperate partition)
