Hi all,

I have a rather "elementary" question: how exactly does gradSchemes specification works?

I need to limit the gradient inside each cell in a fashion similar to the Minmod limiter.

Lurking on this forum I found the cellMDLimitGrad strategy, which has to be coupled with a limiting scheme (Minmod in my case).
On the same post, i found a line like this

default Gauss linear cellMDLimitedGrad Gauss linear 1;

What does it mean? Why is Gauss linear repeated 2 times?
Is it possible to limit the gradient inside each cell so that it has the min abs value of each neighbouring cell, using a standard function, or do I have to code it from scratch?
