Elmer - 基于FEM的多物理场求解器

Posted by on 04/11/2012 in Other Codes | 0 comments

Elmer is an open source multiphysics simulation software mainly developed by Finland's IT Center for Science (CSC). Elmer development started in 1995 as a collaboration with Finnish Universities, research institutes and industry. After it's open source publication in 2005, the use and development of Elmer has become international. Elmer includes physical models of fluid dynamics, structural mechanics, electromagnetics, heat transfer and acoustics. These are described by partial differential equations which Elmer solves by the Finite Element Method (FEM). ElmerSolver has a modular architechture, which makes it easy to extend and maintain. The parallel version of...

Palabos 2012 Challenge

Posted by on 02/20/2012 in PalaBos/OLB | 0 comments

Palabos 2012 Challenge On behalf of FlowKit Ltd, I would like to announce the launch of the Palabos 2012 Challenge. This contest offers rewards for lattice Boltzmann simulations that are achieved with the open-source Palabos library and that solve a problem in a specific applied field. The best submissions get a 1'000 Euro reward (1st prize), one of FlowKit's support formulas for Palabos (2nd and 3rd prize), or a useful office gadget (4th prize). Details about the contest can be obtained at the web address http://www.palabos.org/plb2012challenge . All contributions will be published after the contest and will be available to the community under the terms of an...

OpenFOAM 2.1.0官方版本发布

Posted by on 12/21/2011 in OpenFOAM | 1 comment

时隔半年,在被SGI收购后,现归属SGI/OpenCFD的OpenFOAM小组在2012年12月19日在其官方网站发布了最近的OpenFOAM 2.1.0官方版本。相关信息请参见OpenFOAM官方网站www.openfoam.com。新版OpenFOAM增加了一些新的功能: 任意网格交界面(AMI) 在新版本中采用了全新的可并行的任意网格交界面 (或称“GGI”),可以在模拟中采用滑移交界面和和非连通边界。适用于旋转体几何 (如旋转机械) ,因此方便用户在周期性边界中使用及在不同网格间区域中得耦合计算(如表面膜和体内部流动)。 更多… 多相流模型 发行版包括:...

在创建一个新的基于块结构的格子时,必须通过定义dynamics来保证在每一个格子上执行何种碰撞模型。为了避免在没有使用dynamics对象的情形下出现bugs,构造函数会为所有的格子指定一个默认的dynamics,称之为背景动力学: //创建一个新的块结构格子基于BGK动力学结构 MultiBlockLattice3D lattice( nx, ny, nz,new BGKdynamics(omega)...
