overflow error on linux cluster
 
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

Re: overflow error on linux cluster
 
Could be due to partitioning. To confirm, try running on the linux cluster using the same number of partitions as the local PC. If that works, then look at where your partition boundaries lie on the case that fails.
