Dear all,

A significant part of the last academic year I have been working on the problem of turbulent inflow generation for LES. The key issue is providing correct turbulent structures at the inflow boundaries. Failing to do so can result in long flow adaption lengths or even re-laminarisation.

Many methods have been proposed in the literature, but their implementations are scattered across different CFD codes and are nowhere to be found. As a first building block towards a solution to this problem, I have created a Python package called “eddylicious” which is meant to be a placeholder for various existing methods. Currently it implements the rescaling procedure from (Lund et al, J. Comp. Phys., 1998) that is a powerful inflow generation method for simulations of turbulent boundary layers. The generated fields are saved to disk, so eddylicious can be used with your favorite CFD solver as long as it can read boundary data from the hard drive! The continuation of this work largely depends on collaborative effort of the LES community, so you are welcome to contribute your favorite generation method to the code!

The package lives on github

A thorough User guide and a tutorial for using the package together with OpenFOAM is available here

You can also read more about eddylicious and inflow generation in my licentiate thesis
