This is a simple function that provides a convenient way for a user to
call fvc::reconstruct for the purposes of post-processing flux fields;
e.g., to construct a cell velocity from a face flux.
It can be used to generate output during a run by adding the following
settings to a case's controlDict:
functions
{
#includeFunc reconstruct(phi)
}
Or it can be executed as a postProcessing step by calling:
postProcess -func "reconstruct(phi)"
