Problem with Boundary Conditions using a journal file
 

Hi,
I would like to simulate a flow around an airfoil with different angles of attack and different reynoldnumbers.
The simulation works very well. I decided to use a journal file, so that the different simulations can run at night...

The problem is:
When I start Fluent (6.3.26) and run the journal file, it works. When I run it a second time without restarting fluent, the file is not able to change the boundary conditions (velocity inlet) to simulate the next angle of attack. Everything else works.
I wanted to write one single journal file with the different conditions, but it does not work because of the problem I described above. My journal file is useless if I have to restart Fluent after every single simulation.

My journal file is attached - I tried it with two different angles of attack....


It would be very nice if someone has an idea how to solve my problem!

Thanks,
Till

hi
 

hi.if you want to write a journal file and use it for many times ,i think you can do the following procedure:
write:
solve monitors residual reset yes
and then define new boundary conditions and .......

Thanks for your help vatovato!
