MrFrog New Member Luke Join Date: Jul 2012 Posts: 8 Rep Power: 14	for your standard turbulent incompressible RANS simulations i have seen exmples that limit (usually with leastsquares) all the grad schemes variables. But, in the motorBike tutorial of the examples given in foam-extend, Openfoam and stated in some forum posts they seem to suggest that you should not limit anything other than grad(U). I guess my question is why? whats the accuracy consequences of doing this, and can anyone direct me to example cases or papers that say why this is the case? RodriguezFatz likes this.
