Hi there
I'm now running ANSYS-CFX simulation via HPC cluster at my Uni. I used script file with the below command: cfx5solve -batch -double -def 2cmsteady.def -fullname 2cmsteady -monitor 2cmsteady.res -part $nnodes -par-local But, when I went through the out file, I found this words which means that double precision not active!!! +--------------------------------------------------------------------+ | | | CFX Command Language Upgrade | +-------------------------------------------------------------------- Added /SIMULATION CONTROL/EXECUTION CONTROL/EXECUTABLE SELECTION/Double Precision = Off. +--------------------------------------------------------------------+ | | | CFX Command Language for Run | | +-------------------------------------------------------------------- As well as, I run the same simulation on my own PC, and there is different between the resdual for both. So how I can run my simulation via hpc cluster with double precision to avoid run-off error!!! Finally, if I misunderstand any thing, please, tell me the meaning of this Double Precision = Off. Regards |

I thought that setting double precision at the commend line over-rode any setting from CFX-Pre but your comment suggests this is not so. In that case I would open it in CFX-Pre and toggle th double precision to on.
