NOGRID
From CFD-Wiki
NOGRID FPM is a commercial CFD code. It is a product of NOGRID GmbH.
Current version is 4.0.0 (at June. 1, 2009).
NOGRID FPM is one of the latest technologies in the area of numerical flow simulation. FPM can excellently be applied in the case of all problems, where grid-based methods reach their limits. Examples are fluid dynamical problems with free surfaces, moving parts, multiphase flows, fluid-structure interactions with a strong change of the computing domain or mechanical problems with substantial structure changes.
Nogrid's Finite Pointset Method (FPM) is software for simulation tasks in a wide area of flow and continuum mechanical problems and is based on a method, which use a local defined, non-stationary point cloud distribution for discretization of the Navier-Stokes equations. This point cloud is generated automatically by the software depending on users settings. Thus there is no need to generate a mesh as required in classical CFD methods. FPM points are automatically filled, moved, refilled and cleaned depending on user specifications. The point cloud can be defined variously, e.g. constant in the whole flow domain, changing with time or increasing/decreasing locally depending on the flow/geometry situation.
