Dear fomers

I have been using pisoFoam for high Reynolds number flow over a cylinder simulations. At the moment, I am trying to run some low Reynolds number cases with a DNS solver. The dnsFoam is for box turbulence case with extra forcing term in it. However, I lloked at the icoFoam source file and it seems quite similar to the dnsFoam without the forcing. Does this mean icoFoam is a DNS solver or I am completely wrong?

Thanks

icoFoam is a solver without any modelling for turbulence.

So it can be used for a laminar flow, or for a DNS. However, it will of course only be a DNS if your mesh will allow this etc. etc.
mgg and Mehrez like this.

Hi stevenvanharen, Thanks for the speedy reply. Regarding to the mesh, you are saying it will only be a DNS is the mesh is designed for a DNS simulation?

Thanks

should we except exactly same result if we solve a laminar case by icoFoam and dnsFoam?
Because there is an extra source term in dnsFoam...
