rhoSimplecFoam laminar?
 
Hey Foamers,

This may seem like a dumb question but I can't figure it out.

Can rhoSimplecFoam perform laminar simulations?

I would assume that it could and tried it for one of my other cases yet I could not get it to run without turbulence. Also, when I go to the "squareBend" tutorial and change the "simulationType" to laminar in the "turbulenceProperties" dictionary it continues to run the simulation with the RASmodel. If I delete the "RASProperties" dictionary it gives me an IO error indicating it can't find the directory.

Any ideas?

I feel like I must be overlooking something really trivial but its really frustrating me!

Thanks for your help.

Hi,

rhoSimplecFoam can do laminar runs. Have a look at the solver output. The solver should not solve any turbulence model eqn.

If you want to be sure, create a new volScalarField in the solver and output the laplacian term of the velocity equation.

About the RASProperties file, I not ssure about that but inthe RAS model folder is a laminar model, maybe have a look at that.


Best Regards,
Christian

Hey Christian,

You were correct. Thanks for your reply and assistance.
