NOGRID FPM is a commercial CFD code. It is a product of NOGRID GmbH.

Current version is 3.61 (at Okt. 1, 2008).

Nogrid's Finite Pointset Method (FPM) is software for simulation tasks in a wide area of flow and continuum mechanical problems. FPM is a particle method, i. e. a grid-free method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, does not require a grid or mesh.

FPM can excellently be applied in the case of all problems, where grid-based methods reach their limits due to the necessary remeshing. Examples are fluid dynamical problems with free surfaces, multiphase flows, fluid-structure interactions with a strong change of the computing domain, or structure mechanical problems with substantial structure changes.

FPM is a most modern technology based on a particle method to solve the Navier-Stokes equations. Using the fast and robust FPM solver the usual long modelling and computing times can be shortened substantially.

Increase your added value and secure your competitive advantage!

* Extremely short modeling time * Dramatically reduced computing time * Easy data exchange to existing CFD/CAE environments * Direct import of models from CAD-Systems

Why meshless modeling with Nogrids FPM?

Our FPM (Finite Pointset Method) software is based on the so called particle method. Contrary to classical methods this method requires no mesh for the discretization of differential equations. 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.

The main advantages of our FPM software are

* Easy modeling of all free surface problems * Simple representation of multiphase flows within FPM * Natural interface for the description of moving parts and boundaries * Straightforward solutions for Fluid Structure Interaction (FSI) tasks * Very short computation time in comparison to classical methods without reducing results quality * Direct import of models from your CAD system without mesh generation
