mpirun detected that one or more processes exited with non-zero status

在应用pisoFoam计算燃烧室冷态流场时出现下面错误，而且每次都是计算一段时间后才出现。请问大家遇见过这个问题么?具体该怎么解决呢？
PS：本人目前应用的360核进行并行计算，目前已经排除了时间步长的问题。附图为log中的迭代错误，附件txt文件为err详细信息。 -
@香柏树 朋友，这个问题处理掉了吗。我的算例在计算时也出现这样的报错了。报错内容如下：
Primary job terminated normally, but 1 process returned a non-zero exit code. Per user-direction, the job has been aborted. -------------------------------------------------------------------------- -------------------------------------------------------------------------- mpirun noticed that process rank 5 with PID 0 on node hpws09 exited on signal 8 (Floating point exception). -

请问您是重新计算 还是只计算最新几步的结果
我删除了最后几个时间步 重新计算 依旧迭代不出来PIMPLE: iteration 1 Updating StokesI wave model for patch inlet smoothSolver: Solving for alpha.water, Initial residual = 2.85603060095e-08, Final residual = 1.44420404532e-10, No Iterations 1 Phase-1 volume fraction = 0.66661826176 Min(alpha.water) = -5.22905791777e-10 Max(alpha.water) = 1.00014678682 MULES: Correcting alpha.water MULES: Correcting alpha.water Phase-1 volume fraction = 0.66661826176 Min(alpha.water) = -5.22905791774e-10 Max(alpha.water) = 1.00014678682 Updating shallowWaterAbsorption wave model for patch outlet GAMGPCG: Solving for p_rgh, Initial residual = 0.833496905521, Final residual = 5.36596999747e-06, No Iterations 9 GAMGPCG: Solving for p_rgh, Initial residual = 0.748404838772, Final residual = 4.322497918e-06, No Iterations 9 time step continuity errors : sum local = 6.40365228609e-12, global = -3.66804749067e-13, cumulative = 2.06361704946e-05 GAMGPCG: Solving for p_rgh, Initial residual = 0.804959354481, Final residual = 4.4360097837e-06, No Iterations 9 GAMGPCG: Solving for p_rgh, Initial residual = 0.834220247626, Final residual = 4.86674559877e-06, No Iterations 9 time step continuity errors : sum local = 2.88518833016e-11, global = -4.33468036047e-13, cumulative = 2.06361700612e-05 smoothSolver: Solving for omega, Initial residual = 8.63899230563e-07, Final residual = 4.28995095404e-10, No Iterations 2 smoothSolver: Solving for k, Initial residual = 4.09430928447e-06, Final residual = 1.30320142023e-09, No Iterations 2 ExecutionTime = 232.9 s ClockTime = 234 s Courant Number mean: 5.31856748554e-06 max: 6.80956597246 Interface Courant Number mean: 4.94232067864e-07 max: 6.80956597246 deltaT = 2.06579061066e-06 Time = 67.1303 PIMPLE: iteration 1 Updating StokesI wave model for patch inlet smoothSolver: Solving for alpha.water, Initial residual = 1.69468041505e-08, Final residual = 5.40084448828e-11, No Iterations 1 Phase-1 volume fraction = 0.666618261841 Min(alpha.water) = -4.88357838579e-10 Max(alpha.water) = 1.00014678669 MULES: Correcting alpha.water MULES: Correcting alpha.water Phase-1 volume fraction = 0.666618261841 Min(alpha.water) = -4.88070715976e-10 Max(alpha.water) = 1.00014678669 Updating shallowWaterAbsorption wave model for patch outlet GAMGPCG: Solving for p_rgh, Initial residual = 0.856084241578, Final residual = 3.91327711378e-06, No Iterations 9 GAMGPCG: Solving for p_rgh, Initial residual = 0.729556404756, Final residual = 4.52724813344e-06, No Iterations 9 time step continuity errors : sum local = 4.23132086572e-12, global = -1.39652678751e-13, cumulative = 2.06361699215e-05 GAMGPCG: Solving for p_rgh, Initial residual = 0.824421265103, Final residual = 5.74632165117e-06, No Iterations 9 GAMGPCG: Solving for p_rgh, Initial residual = 0.858181339411, Final residual = 6.32297321249e-06, No Iterations 9 time step continuity errors : sum local = 2.37161385914e-11, global = -7.86308500369e-13, cumulative = 2.06361691352e-05 smoothSolver: Solving for omega, Initial residual = 5.2565171788e-07, Final residual = 3.49278374392e-09, No Iterations 1 smoothSolver: Solving for k, Initial residual = 2.66135012542e-06, Final residual = 7.33859698627e-11, No Iterations 2 ExecutionTime = 257.81 s ClockTime = 259 s Courant Number mean: 3.23080344243e-06 max: 4.63861488263 Interface Courant Number mean: 2.53529659665e-07 max: 4.63861488263 deltaT = 4.45346458291e-07 Time = 67.1303 PIMPLE: iteration 1 Updating StokesI wave model for patch inlet smoothSolver: Solving for alpha.water, Initial residual = 1.28408799391e-08, Final residual = 1.08364680021e-11, No Iterations 1 Phase-1 volume fraction = 0.666618261848 Min(alpha.water) = -4.66529651265e-10 Max(alpha.water) = 1.00014678621 MULES: Correcting alpha.water MULES: Correcting alpha.water Phase-1 volume fraction = 0.666618261848 Min(alpha.water) = -4.66080169839e-10 Max(alpha.water) = 1.00014678621 Updating shallowWaterAbsorption wave model for patch outlet GAMGPCG: Solving for p_rgh, Initial residual = 0.876222984413, Final residual = 4.82480308588e-06, No Iterations 9 GAMGPCG: Solving for p_rgh, Initial residual = 0.76986420467, Final residual = 5.12962944087e-06, No Iterations 9 time step continuity errors : sum local = 4.52648844462e-12, global = -1.38478426638e-13, cumulative = 2.06361689967e-05 GAMGPCG: Solving for p_rgh, Initial residual = 0.845759428026, Final residual = 5.01065970515e-06, No Iterations 9 GAMGPCG: Solving for p_rgh, Initial residual = 0.874705259624, Final residual = 4.63805995333e-06, No Iterations 9 time step continuity errors : sum local = 1.00680418755e-11, global = -1.63755700805e-13, cumulative = 2.0636168833e-05 smoothSolver: Solving for omega, Initial residual = 2.70184710423e-07, Final residual = 2.50452634116e-10, No Iterations 1 smoothSolver: Solving for k, Initial residual = 1.28659289894e-06, Final residual = 1.3294530894e-09, No Iterations 1 ExecutionTime = 282.65 s ClockTime = 284 s
