Title:Got PDEs to solve? Try the open source computational physics platform OpenFOAM
Seminar:CCMA Luncheon Seminar
Speaker:Xiaofeng Liu, Department of Civil and Environmental Engineering, PSU

Abstract:
The talk will showcase some modeling work for various physics problems (mainly in fluid mechanics) using the open source computational physics platform OpenFOAMĀ®. It has been more than ten years since OpenFOAMĀ® entered the public domain. The user base has grown tremendously evidenced by the active online community and the increasing publications. This platform is essentially a computational toolbox which solves mathematical models (partial differential equations, PDEs) using finite volume method. OpenFOAM solves the PDEs in an automatic fashion and yet provides sufficient user controls on almost all aspects of the numerics, for example discretization schemes. Parallel computation based on domain decomposition is also automatic since the mechanism is built into the lower level of the code structure. Upper level users do not need to know the details. It liberates the researchers from the burden of extensive computer coding and makes it possible for them to focus on the physics. From the abstraction of physical processes to mathematical models, to implement them in OpenFOAM and see the results, a proficient user probably only needs several hours. Our research group has used it for a variety of problems, including river and coastal hydraulics, porous media flows, sedimentation, buoyant plumes, etc.
