activeBarriers computes material active barriers to the transport of momentum and vorticity for flows defined on a three-dimensional cartesian grid
This repository is the reference implementation of the active barriers for a turbulent channel described in
G. Haller et al., "Objective material barriers to the transport of momentum and vorticity", submitted to Journal of Fluid Mechanics, 2020
The computation is divided in two steps, each of them provided as a separate program:
- barrierField.cpl: the computation of the three-dimensional active barrier field from velocity data
- ftle.cpl: computation of aFTLE/aPRA diagnostic for the active barrier field
