NOGRID FPM is a commercial meshless CFD code. It is a product of NOGRID GmbH.
Current version is 4.1.3 (at Jan. 1, 2011).
FPM can 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 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.
