OpenFoam Now with Fedora RPMs

Well, I was pretty excited that OpenFoam was acquired by SGI, and they created a foundation to hold the copyrights for the project. That is good news for building a healthy open source community around the software. Looks like I jumped the gun with the install from source option I detailed back in November. If only I were a little more patient, I could have installed from rpms. The new release has lots of interesting additions. We live in exciting times for open source CFD.

  1. A couple interesting sounding presentations at an upcoming workshop on overset grids.

    OverFOAM: Preliminary Development of an Overset OpenFOAM Solver for Wind Turbine Applications
    Hybrid codes that couple a near-body RANS solution to a vortex-based wake solution are of great interest for modeling the types of complex interactions that exist in wind turbine and wind farm analyses. This project has added overset capability to the OpenFOAM open-source framework to allow for the future development of a hybrid code. This has been accomplished by the development of a new overset library that can be linked with an OpenFOAM solver to allow the solver to interface with the Suggar++ and DiRTlib libraries developed by Ralph Noack. Suggar++ determines how the overset meshes exchange information through donor interpolation and flagging of cells that are outside of the solution domain. DiRTlib uses the connectivity information supplied by Suggar++ to execute the exchange of information between the meshes. The overset capabilities have been tested on dynamic, overset meshes. Applications of interest include rotors and wind turbines.

    An ALE Based, overset mesh FSI method
    Existing overset mesh technology has been incorporated into an ALE based fluid-structure interaction code, producing a novel approach for investigating fully-coupled FSI phenomena without many of the common problems associated with the mesh motion. In particular, the Suggar++/DiRTlib overset mesh technology has been implemented into a partitioned FSI solver based on OpenFOAM and in-house structural codes. The benefits of using overset meshing for FSI applications are improved solver efficiency, better mesh quality, and simplified mesh generation. Comparisons to other academic and commercial solvers have been performed, and used as validation and benchmarking for the overset solver. Results of comparison to the Turek-Hron FSI benchmark case, as well as parallel scaling data are presented.
