磨具应力分析出错

在笔记本上做磨具应力分析，进行到2.44%是报警，到处报警信息内容如下： Unable to obtain the memory requested during a dynamic
memory request. This can be due to the following reasons:
1) The maximum allowed amount of memory is exceeded.
This can be set in the solver option for certain solvers.
See Volume C, solver model definition option.
2) There is not enough free memory on the system.
If the memory available is not enough for an in-core
solution, Marc will attempt to perform the
solution out-of-core. In this case, some data which
normally would be stored in memory is stored on the hard
disk (which could slow down the analysis considerably).
The memory request will fail if there is still not enough
memory for the analysis.
翻译后大意是：无法获得请求的内存在一个动态的
内存请求。这可能是由于以下原因：
1）允许的最大内存量超标。
某些求解器的求解器选项中可以设置。
见C卷，求解模型定义选项。
2）系统上没有足够的可用内存。
如果可用内存是不够的，一个核心
解决方案，Marc将尝试执行
解决方案的核心。在这种情况下，某些数据
通常会被存储在存储器中的存储在硬盘
磁盘（可能大大减慢分析）。
如果仍然不够，内存请求将失败
内存中，以供分析。
看来好像是内存不足导致的，但是我的笔记本内存是2G的，应该是够用了。请大家帮忙。
