Hi, I am struggling with setting up the gradient schemes.

According to the manual, I am supposed to use an interpolation scheme after "Gauss". I used "linear" and "upwind". Both are alright. But I tried to use a limiter in the interpolation scheme and things got a bit weird and don't work:

grad(p) cellMDLimited Gauss linearUpwind phi 0.8;
grad(p) Gauss vanLeer01 phi;
grad(p) cellMDLimited Gauss vanLeer01 phi 1;

Basically none of the three inputs above works. Could someone explain what goes wrong? I can't really follow this bit of the code as I didn't manage figure out the parameters needed from the contructors.. Please someone help me with that. Thank you in advance.
