Dear all,


For some years now, me and my colleagues have been working on implementing a library of wall models for LES, expanding the native capabilities of OpenFOAM. In the latest release, v0.4.0, we have added support for the latest versions of OpenFOAM, both Foundation and OpenCFD releases. It is thus a good time-point to (re-)introduce the code to the community.


The library can be found here

https://bitbucket.org/lesituu/libwallmodelledles

The README file provides quite a bit of information about what the library does, I copy the Key features section below
  • Provides a number of wall models, based on both non-linear algebraic and ordinary differential equations, see the class-headers in the wallModels folder.
  • Makes it possible to specify the distance to the wall model's sampling point, h, on a per-face basis.
  • Allows the user to control all the other parameters of wall modelling, e.g. model constants, iterative solver settings etc.
  • Serves a as a convenient framework for implementing new models without a lot of code duplication.
An in-depth discussion along with simulation results for turbulent channel flow and flow over a BFS can be found here.
https://arxiv.org/abs/1807.11786
More works using the library can be found in the end of the README.


For obvious reasons, it has not be possible to thoroughly validate the code using all the supported OF versions. Therefore any issues with compilations and running are very welcome to be reported. Please also feel free to contact me regarding any possible collaborations, WMLES is becoming a hot topic, and joining forces is usually of benefit.

Hi Timofey,

Really great work with this! I've been playing around with it and have been pleased with my early testing. Thanks so much for making this publically available to the community. Is there a foam-extend version available or in the works?

Hi!
Great to hear that it's working out for you. foam-extend support is not really in the making at the moment. Unfortunately, I have no experience with that fork, but I can imagine that for someone who does it would be pretty easy to make the adjustments! In any case, the fact that you request it is a push towards me considering to spend time on it . It won't be quick though, since I have other developments in the pipeline, which have higher priority.
