最近在做fluent的并行计算,收集了很多资料,但还是迟迟不能成功,恳请高手不吝赐教!下面是我所遇问题的描述:
1.我安装了rshd,在dos命令中输入C:\Fluent.Inc\ntbin\ntx86\fluent.exe -r6.3.26 3d -t2 启动fluent的并行版本,读入cas和dat文件,auto partition--->load balance--->initialize--->iterate,出现如下报错信息后终止计算:
iter continuity x-velocity y-velocity z-velocity time/iter
1 1.0000e+00 2.4150e-06 0.0000e+00 0.0000e+00 0:08:12 99

这是什么意思呢?
2. 在采用上述设置时,有时候也可以计算,偶尔会有提示说信息传递成功,但是时断时续,很不稳定,请问这要怎么解决?为什么有时候又出现问题1那种情况呢?
3. 听说要安装mpi,于是我依提示安装,可是在注册时出现错误“应用程序正常初始化(0xc0000135)失败”,我不知道这是为什么,很苦恼哇...请求高手帮帮我...
我的电脑配置是双核,2G内存,系统是xp |
