Interpolation schemes are used to transform cell-centre quantities to face centres. The operation is used in many of the finite volume calculations, e.g. for the calculation of gradient, divergence, and Laplacian terms.
Usage🔗
Interpolation schemes are specified in the
fvSchemesfile under the interpolationSchemes
sub-dictionary using the syntax:
interpolationSchemes
{
default none;
<equation term> <interpolation scheme>;
}
Options🔗
A wide variety of interpolation schemes are available, ranging from those that are based solely on geometry, and others, e.g. convection schemes that are functions of the local flow.
