并行计算的问题

aleisia

我的平行计算，出现下列问题， 我用的是win7 64位系统，4核cpu，14G内存，用sdk7.0的cmd shell来启动x64的fluent，没问题，可是设定了4个线程，编译和load udf都没问题，可是并行计算的时候总是出现下面的提示：

Updating solution at time level N... done.
  iter continuity x-velocity y-velocity z-velocity     energy          k    epsilon        tep     time/iter
MPI Application rank 2 exited before MPI_Finalize() with status -1073741819

999999 (..\src\mpsystem.c@1149): mpt_read: failed: errno = 10054

999999: mpt_read: error: read failed trying to read 4 bytes: No such file or directory
The Parallel FLUENT process could not be started.
按照网上的说法，是开始用serial来算一下，保存case之后再用并行来计算，可是我换成serial后，错误如下：
Error:
FLUENT received fatal signal (ACCESS_VIOLATION)
1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.

Error:

1. Note exact events leading to error.
2. Save case/data under new name.
3. Exit program and restart to continue.
4. Report error to your distributor.
Error Object: #f

网上的说法是，内存不够或者网格有问题。可是我都把我的网格都设为很少的网格数了，我感觉哪怕是网格数减少到了11万，还是出现上述的serial问题... 这样的话我不能用serial开始计算，也就不能解决上面的并行的问题，请问大家我该如何办？

不管是串行还是并行，编译udf都没问题，例如：
Deleted old libudf\win64\3ddp\libudf.dll
        1 file(s) copied.
(system "copy "C:\ANSYSI~1\v121\fluent"\fluent12.1.4\src\makefile_nt.udf libudf\win64\3ddp\makefile")
        1 file(s) copied.
(chdir "libudf")()
(chdir "win64\3ddp")()
# Generating ud_io1.h

# Generating udf_names.c because of makefile test3.obj

你可以吧UDF去掉看下有没有问题
先排除有没有可能UDF并行是出错了
祝好运！
