INS2d and laminar flow

Felipe

Hi, I have used the incompressible navier stokes solver INS2d with a turbulence model to resolve flows around airfoils, results were pretty good. However I am interested in running some laminar cases at very low Re <10k. I know that the code can run in fully laminar mode, however I can't seem to find how to do this. Can somebody help me? Do I need to use a flag not listed in the manual , please help

Thanks, Felipe
