物理内存2G，但pre_memory只能设到1200M。求教!

我的机器是2G的内存，但是standard_memory设到大于1200M时就出现如下错误。 监视系统中内存分配情况没发现什么问题，不知道朋友们有没有碰到这种情况的，大家谈谈看法。谢谢了!

看ABAQUS DOC就知道了
The maximum amount of memory that can be allocated by the ABAQUS/CAE and ABAQUS/Viewer kernel. If the limit is exceeded, ABAQUS/CAE displays an error message. The abq_ker_memory must be specified in MB (megabytes) and is used only for 32-bit systems. For Windows 32-bit systems the default is 1800 MB; for Linux 32-bit systems the default is 2800 MB.

Increasing the memory limit is not recommended unless you are using a Windows 32-bit system with the boot option /3GB /userva=SizeInMBytes to extend the amount of memory available for ABAQUS/CAE. In this case the limit can be changed to 2800 MB (the same as Linux).
