Hello,
I am trying to solve a two-phase flow with VOF on a cluster in batch mode with 4 cores. It's a simple problem of a 2 dimension (2-D) dambreak. At the initialisation time, I have a rectangular domain with the half of water on the left side and the other half of air at the right side. I have this error message: Primitive Error at Node 0: set_domain_residuals: not enough memory. My mesh is 500 elements on x direction and 100 elements on y direction. So, it a total of 50 000 elements for all the domain. I don't know if there is an an option to distribute the memory in batch mode. My command line is: time fluent 2ddp -ssh -t4 -pethernet -cnf=/home/mtoure/dambreak/hostfile -g -i <fluent_case.jou>& fluent_case.out & The fluent_case.jou is: ; Journal file for FLUENT ; Read case and data files rc /home/mtoure/dambreak/FFF.cas rd /home/mtoure/dambreak/FFF.dat ;to specify the reporting interval you use: /solve/set/reporting-interval 10 ;to specify the time step size you use the command (in second): /solve/set/time-step 0.001 ;to specify the number of time step and inner iteration you use: /solve/dual-time-iterate 2400 ; Write data file wd example2400iter.dat ; Exit FLUENT exit yes Thank you for your help. |

My command line is:
fluent 2ddp -ssh -ssh -t8 -g -i <fluent_case.jou > fluent_case.out The journal file is: ; Journal file for FLUENT of a transient flow cd /sb/home/mtoure/dambreak4 ; Read case and data files /file/read-case FFF.cas /file/read-data FFF.dat ; To specify the data autosave frequency (100) /file/autosave/data-frequency 100 ; To specify the case autosave frequency ;/file/autosave/case-frequency 0 ; To specify the the root name of the data files or case files /file/autosave/root-name FFF ; Initialize the solution ; /solve/initialize/initialize-flow ; To specify the reporting interval you use (10): /solve/set/reporting-interval 10 ; To specify the time step size you use the command (in second): /solve/set/time-step 0.001 ;to specify the number of time step (exemple 2400) and inner iteration you use: /solve/dual-time-iterate 2400 ; Write data file /file/write-data Data2400iter.dat ; Exit FLUENT exit yes |
