 October 9, 2013, 10:55 can slip boundary condition in openFoam mean "inviscid wall" ? #1 Senior Member   saeideh mohamadi Join Date: Aug 2012 Posts: 229 Rep Power: 14 Hi I am simulating the flow over an multi element airfoil, i have studied in a research that for simulating the correct experiment conditions "we should reat the wind-tunnel walls as inviscid walls" now my question is that, how can i define the "inviscid wall" in openFoam? if we set slip boundary condition for the top and bottom side of our domain,can this boundary condition in openFoam mean "inviscid walls" ? i mesh a squre domain around my sirfol, i put the freestream for the inlet and outlet patch (left and right side), i don't know what boundary condition should i use for topAndBottom side! please guide me Thank you very much

Thank you, but my question is that, how can we chose inviscid wall for topAndBottom ?
