The important steps in the development of MHD codes starting from the 1970s are outlined first and then basic MHD codes, which are currently in use by designers of liquid breeder blankets, are reviewed. A benchmark database of five problems has been proposed to cover a wide range of MHD flows from laminar fully developed to turbulent flows, which are of interest for fusion applications: (A) 2D fully developed laminar steady MHD flow, (B) 3D laminar, steady developing MHD flow in a non-uniform magnetic field, (C) quasi-two-dimensional MHD turbulent flow, (D) 3D turbulent MHD flow, and (E) MHD flow with heat transfer (buoyant convection). Finally, we introduce important details of the proposed activities, such as basic V&V rules and schedule. The main goal of the present paper is to help in establishing an efficient V&V framework and to initiate benchmarking among interested parties. The comparison results computed by the codes against analytical solutions and trusted experimental and numerical data as well as code-to-code comparisons will be presented and analyzed in companion paper/papers.} +} + +@misc{nasa-web, + title = {Turbulence Modeling Resource}, + note = {Langley Research Center}, + url = {https://turbmodels.larc.nasa.gov/}, + year = {2024} } \ No newline at end of file diff --git a/paper/paper.md b/paper/paper.md index f797398..9697c32 100644 --- a/paper/paper.md +++ b/paper/paper.md @@ -47,7 +47,7 @@ As part of the VERTEX initiative, the primary mission of the VERTEX-CFD team is # Current capabilities and development workflow -VERTEX-CFD solver is still under active development and currently implements the following capabilities: incompressible Navier-Stokes equations [@Clausen2013], temperature equation, induction-less and full-induction MHD models, RANS turbulence models and WALE (LES) [@nicoud:hal-00910373] turbulence model.

It was found that strong and weak scaling were comparable to other CFD solvers alike NekRS. (ADD FIGURE). The long term objectives of the VERTEX initiative is to facilitate the addition of new physical models by relying on a plug-and-play architecture, and also guarantee the correctness of the implemented model over time. New physics and equations are easily added to the global tree and allow for quick deployment of new physical model on HPC platforms. Such approach can only be made possible by setting clear requirements and review process for all developers contributing to the project code: any changes and additions to the source code is reviewed and tested before being merged. VERTEX-CFD solver is tested daily on a continuous integration (CI) workflow that is hosted on ORNL network.
