      直接在进入界面打开parallel 可以设置process数,想问一下process是根据电脑核数确定的吗?比如24核,那是不是最合适的是输入23(留一个给其他)?

      我这个样子操作进去以后,但是看到consoll类似下面提示:
      Note: Rank = 15: Process affinity not being set (3),感觉好像对计算没有影响,这个问题是怎么产生的?

      我在这个cas里算完之后,把data导入新的cas里继续第二部计算的时候出现
      read_thread_data_section: invalid thread id 19. 这是为啥?

      计算完一个时间步长的时候发现停止了,提示
      Node 20: Process 10672: Received signal SIGSEGV.

      MPI Application rank 0 exited before MPI_Finalize() with status 2
      The fl process could not be started.

      求大侠指点:chouchou:

        可能的原因是线网络断开,我出现过几次,fluent无法写数据,无线网处于断开状态

          服务器有别人用,开了多个fluent,或者上个fluent进程没杀死完?
