Can you 'turn off' the non-linearity in OpenFOAM solvers?

odellar · December 10, 2016, 07:30

Hi,

I'd like to run some linear simulations. I use pimpleFOAM with a one equation k-equation subgrid scale model (LES). Is there a way of 'switching off' the non-linearity in the equations/solver?

I just want the non-linear term in the equations to be removed.

Thanks,

Olie

If I understand you correctly, you want to remove the convection term in the NS equations? You can do that by removing this term in the solver in the pimpleFoam files and saving it as a new one.
