How to get CPU time and flops

Hi there,
Im interested in the solver performance itself. My question is how to get the CPU time, as well the flops operation, memory allocation, and so on. That is to say if it's possible to get a profile (as in matlab or in c++) of the solution. Greetings, Joel |

What operating system?
On unix, programs like "top", "ps", and "time" will be useful. On windows you probably want to bring up the task manager, (press ctrl-alt-del) and turn on all the columns You may get some useful information out of fluent itself. Rob |

Hi, You can get the CPU time by run fluent in parallel mode and type in TUI "parallel timer print" //Kalle

Hi,
For serial run, you can use the following TUI command that is executed before and after the iteration period of interest: (solver-cpu-time) • The difference is the elapsed CPU time in seconds for the iteration period completed |

I was running a 3D, double-precision, steady-state simulation in parallel mode and I noticed that the output window provides time/iter in addition to the turbulence and transport variables. I am trying to understand what this actually represents since, I couldn't find it anywhere on the Manuals or User guides.
These values seem to be in a format XX:YY:ZZ and they are updating quite rapidly so I don't know whether this refers to minutes, seconds, total time or something different entirely. I have attached the image so please explain what this represents and whether it is a good way to capture the solver time or duration.

Hi,
This comes 5 years late, but you can find the anwser to what is the use of time/iter in this other thread: Time/Iteration and Time to Convergence FLUENT |
