Not implemented in OpenFOAM - basically because (in my opinion) it's rubbish.

There is a whole bunch of second-order schemes but no limited gradient-extrapolated one like Mars. If you want to do it yourself, take something like SFCD and instead of using cell centre values in the limiter, do a one-sided extrapolation to the face using the cell gradient.

sushant and Amit Mathur like this.
