What is the academic reference of the implementation for Foam::anisotropicFilter?

Question

OpenFOAM (the latest versions at the time of writing) provides three types of test filter for large eddy simulation applications:

1. simpleFilter
2. laplaceFilter
3. anisotropicFilter

Considering there are various anisotropic filters proposed in the literature, could anyone tell us which reference was used in the code implementation of the anisotropicFilter, as such information is not available through the code guide?

Answer 1

The answer was kindly provided by Henry Weller in response to a feature ticket:

The anisotropic filter was not implemented with reference to any literature.
