error pimpleFoam
 

hello,


i am trying to do a karman vortex 2d laminar transient simulation using pimpleFoam, I have the mesh and the dictionaries ready and set, but I receive this error when running pimpleFoam and I am not sure why...


keyword div((nuM*grad(U))) is undefined in dictionary "/rwthfs/rz/cluster/home/jg235250/cylinder/system/fvSchemes/divSchemes"



+++++++++++++++


I have the standard div schemes set in fvSchemes...


divSchemes
{
default none;

div(phi,U) Gauss linearUpwind grad(U);
div((nuEff*dev2(T(grad(U))))) Gauss linear;
}

Can someone please explain why I need the nuM*grad(U) term in my schemes ?


Thanks!
