hi,

I am conducting a compressible CFX10 simulation. The weired thing is, the simulation runs ok on the local PC, but always fails on linux cluster. The error information is overflow.

How to fix it? Thanks a lot

Equation | Rate | RMS Res | Max Res | Linear Solution | U-Mom | 0.00 | 1.3E-12 | 3.7E-11 | 4.7E+08 F | V-Mom | 0.00 | 9.2E-12 | 1.5E-10 | 2.4E+08 F | W-Mom | 0.00 | 3.6E-12 | 7.2E-11 | 6.3E+08 F | P-Mass| 0.00 | 4.2E-22 | 2.0E-20 | 9.3 4.5E+08 F |

ERROR #001100279 has occurred in subroutine c_fpx_handler: Floating point exception: Overflow

Try running benchmark.def with two partitions on the cluster to eliminate it as the source of the problem.

hi, thanks! Can you explain more in detail how to fix it? Also, we don't have parallel simulation license on either pc or cluster.

Test benchmark.def serially on both your windows machine and linux cluster to get a baseline going.

what is benchmark.def? A test case simulation? Previously, our cluster always ran very well with CFX10. This is the first time I have this trouble.

Check the /examples directory. It's there in CFX 11.0, not sure about 10.0, but assume so.
