Interpolation schemes

Table of Contents

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 fvSchemes file 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.
