Laminar and turbulent regions-imposed transition
 
1 Attachment(s)
Dear OpenFOAM users,
I have to impose transition points from laminar to turbulent on an airfoil, using Spalart-Allmaras model in OpenFOAM 2.2.0. Can I split my mesh, to turn turbulence off in a laminar region, without compiling user defined functions?

Can I constraint nut to zero in some cells (laminar region) by the means of fvOptions? E.g.

fixedNut
{
type explicitSetValue;
active true;
selectionMode cellZone;
cellZone porosity;
...............
}
thanks in advance
