Hi!

I'm trying to figure what the parameter psi that can be specified for e.g. the limitedLinear or vanLeer interpolation schemes really do:
default vanLeer psi;

The UserGuide says:
"Some TVD/NVD schemes require a coefficient psi,0 < psi < 1, where psi = 1 corresponds to TVD conformance, usually giving best convergence and psi = 0 corresponds to best accuracy."

Is it some blending between CD and the TVD scheme or ...?

Regards,
