Dear Foamers,


Is it possible to have a conditional entry for a divergence scheme based on Courant number?


For example is something like this entry possible?

divSchemes
{
default Gauss linear;
div(phi,e) #codeStream{
codeInclude
#{
#include "fvCFD.H"
.....
//other necessary compilation files

#};

code #{
word scheme("Gauss linear");
if (maxCo > 0.9)
scheme = "Gauss MUSCL"
os << scheme;
};
};
}

Thanks in advance for your time,
JBR

Yes. The CoBlended scheme allows you to specify switching numerical schemes based on the Courant Number... and a linear blending in between.

Exactly what I was looking for! Thanks a lot Tobi.
