pressure-velocity-coupling in batch mode
 

Hello,

I want to use the pressure-velocity-coupling method (Solve-Controls-Solution-Pressure-Velocity-Coupling: Coupled) but I want to define this setting via Journal-File.

I have tried to use

solve set p-v-coupling

in shell. But this way the p-v-coupled solver is not activated.

How can i activate this solving-method in bat-mode.

Thank You.

Re: pressure-velocity-coupling in batch mode
 

Try this command(s): ;begin solve/set p-v-coupling 23 ;end

where the different schemes are as following: 20 SIMPLE 21 SIMPLEC 22 PISO 23 Coupled You can also check this by drilling down in the TUI and you should be able to replicate the above set of commands.

Regards, Remus

Thank you for your message.

I have tried this way several times. The Problem is, that in the GUI (solve - controls - solution) the coupling method isn´t displayed after i try to enable it like this.

Can it be, that the coupling is enabled, but it is noch displayed there, either?

How can I check if the coupling is enabled?

Thank you.

I've used the same command many times before in batch mode but always used 24 rather than 23 (I only used 24 as it worked from trial & error) and I've had no problems

To get a summary of all settings, BCs, solver controls and more you can type this:

report summary

It is going to ask whether you want it exported to a file. Then you can open the file and look under Solver Controls for the Pressure-Velocity coupling. It's going to show the coupling method.

However, it is only when you're trying to change the P-V coupling through journaling that you don't get to see the P-V window switch in the GUI?

Hello,

thank you for your help. I have tried it out and it works.

Thank you very much.

commands for pressure velocity couple algorithms in TUI
 

solve / set p-v-coupling 20 #SIMPLE
solve / set p-v-coupling 21 #SIMPLEC
solve / set p-v-coupling 22 #PISO
solve / set p-v-coupling 23 #Coupled

For Fluent 19.0, the index for "Coupled" is 24 instead of 23 now.
