电脑内存足够，网格划分不算太多，求解还老是出错
电脑内存原来是8g，后来加装了8g的内存条，网格划分的数量跟加装内存条前差不多，也就15万网格，为什么求解时老是出现下面的问题，上网查了很久，都没查到原因，求大神解救，万分感谢！问题如下：
*** WARNING *** CP = 55.141 TIME= 21:45:50
The Distributed Sparse Matrix Solver is currently running in the
out-of-core memory mode.This memory mode may provide significantly
worse performance compared to the in-core memory mode, depending on
the amount of available system memory and I/O speed.Please monitor
the solver performance to ensure that the large amount of I/O to the
solver files does not create a bottleneck for performance.
*** ERROR *** CP = 98.562 TIME= 21:46:41
An input/output error has occurred while trying to open a file with
length = 3 GB.Error code = 112, which translates to: 磁盘空间不足。
*** ERROR *** CP = 98.562 TIME= 21:46:41
The program is unable to open file file1.DSPtri.If the suggestions in
the associated error messages immediately preceding and/or following
this error message do not help resolve the file issue, please send the
data leading to this operation to your technical support provider,
along with the I/O error code of -1 and the system error code of 0,
for help in determining the possible reasons as to why this file could
not be opened.
*** ERROR *** CP = 98.562 TIME= 21:46:41
An input/output error has occurred on the process with MPI Rank ID = 1.
This error occurs when trying to open a file with length = 4 GB.
Please check to make sure there is enough free disk space in the
working directory (E:\zuijin\anli\_ProjectScratch\Scr5288) on machine
(DESKTOP-J2BGQ1T). 如果你的机器是 32 位的，内存大于 2G 是没有用的。
如果你的机器是 64 位的，可以安装 64 位的软件，应该就不会出现这种问题了。
另一个可能是后安装的 8 G 内存与以前的内存不兼容，需要请专业人员测试一下。 htbbzzg 发表于 2019-7-24 09:02

嗯嗯，谢谢，已解决:loveliness:。原来是之前文件所在的磁盘空间不足，在另外一个磁盘创建文件后再运算就求解成功了，在mechanical里面求解固体结构问题太耗磁盘空间了。 问题解决了就好。
