Hello everybody, can anyone help me with batch files to change solver properties? I want to change from fisrt order to second order in the solution/discretization option with a jou file. How can i get it? Does anyone know? It is possible?

Hey Haritz,

you can change the solver in the journal file itself using the following command

;0->First Order 1->Second Order 4->QUICK 6->Third Order MUCSL /solve/set/discretization-scheme/density 1 ;0->First Order 1->Second Order 2->POWER LAW 4->QUICK 6->Third Order MUCSL /solve/set/discretization-scheme/mom 1 ;0->First Order 1->Second Order 2->POWER LAW 4->QUICK 6->Third Order MUCSL /solve/set/discretization-scheme/temperature 1

Thanks Ravi

Thanks Ravi! But how can i write it in a *.txt file? I want to wrtite a *.jou file using Wordpad. And i would like to iterate 1000 times and then cahnge the solver from first order to second order, and iterate more. I would like to change the pressure inlet also. I konw tha is something like that: /solve /iteration/1000 /define/boundary-conditions/pressure-inlet/..... But i donīnt konw to change the solver order. My aim is to create a file to have the computer working for a few days.

Thankīs for all Ravi.

Is it same as a batch file? If you answer is yes... then you can write it in a .txt file and give this batch file as an input. See more abt running FLUENT in batch mode.

Thanks Ravi
