fluent 15.0迭代不久后莫名出错终止

waouyouy

这两天用服务器上的fluent 15.0（linux_x64）算一个多相流，但是每次迭代到一定步数（每次步数不一定相同），fluent就会自动终止，并出现如下报错：

===============Message from the Cortex Process================================

Fatal error in one of the compute processes.

==============================================================================
MPI Application rank 12 killed before MPI_Finalize() with signal 9

==============================================================================

在cortexerror.log里，显示如下错误：

注：前几天都可以正常计算的，并且昨天问题出现后我已经重装了ansys 15.0,然后把服务器节点也重新启动了，但是还是会出现这种问题，所以想求助下论坛里的老师和同学。
在此表示感谢！
