Fluent 单机多核并行问题

Fluent 单机多核并行的问题

 

1 Windows 平台

 

Fluent 在 Windows 下的单机多核并行很简单，加上启动参数即可。

 

fluent 3ddp -t4

 

启动之后，可以看到多个进程。

 

 

2 Linux 平台

 

目前暂时尝试过的方法：

运行前的准备：

2.1 ssh 服务配置

设置成 key 认证的方式

2.2 写 hosts file

比如运行两个进程

127.0.0.1
127.0.0.1

2.3 运行 fluent

fluent 3ddp -t2 -cns=hosts 3d

下面是命令输出信息：


/opt/progs/Fluent.Inc/fluent6.3.26/bin/fluent -r6.3.26 -g -t 2 -cnf=hosts 2d
