    안녕하세요.
    이번에 Numerical Method에 대해 공부를 하고 있는데, FEM, FVM, FDM 등 여러가지가 있는거 같은데,
    openFOAM에서는 어떤 method 를 사용하고 있는지 궁금합니다.
    특히, simpleFoam- , chtMultiRegion- solvers 등에는 어떤 방법이 적용되는지 궁금합니다.

    openFOAM에서는 FVM(Finite Volume MethodS)를 사용합니다. 앞서 언급하신 solver들도 마찬가지구요.
    http://www.openfoam.com/features 링크 첨부하겠습니다. 아래는 링크한 내용의 일부입니다.

    … OpenFOAM uses finite volume numerics to solve systems of partial differential equations ascribed on any 3D unstructured mesh of polyhedral cells. The fluid flow solvers are developed within a robust, implicit, pressure-velocity, iterative solution framework, although alternative techniques are applied to other continuum mechanics solvers. Domain decomposition parallelism is fundamental to the design of OpenFOAM and integrated at a low level so that solvers can generally be developed without the need for any ’parallel-specific’ coding. …

    Fine님의 링크가 잘못 걸린 것 같네요. 제가 아는 링크 첨부하겠습니다.
