DNS solver confusion
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.

Thanks 
yes, that is what I am saying

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...
