The OpenCFD software series is a high-precision computational fluid
  dynamics (CFD) software developed by the team led by Li Xinliang at the 
  Institute of Mechanics, Chinese Academy of Sciences.
  
  It includes the high-accuracy finite difference software OpenCFD-SC 
  (formerly Hoam-OpenCFD), the multi-block structured grid finite volume 
  software OpenCFD-EC, the high-accuracy simulation software for 
  chemically reactive flows OpenCFD-Comb, and the GPU heterogeneous 
  parallel high-precision computation software OpenCFD-SCU.
  The developers have made this software available for use by scientific 
  research and engineering users.
