NOGRID points software
 in Products
NOGRID points software, based on the meshless Finite Pointset Method (FPM), is a Computational Fluid Dynamics (CFD) software package for simulation tasks in the wide area of flow and continuum mechanical problems. The software doesn't solve only fluid flows, but also problems with elastic or plastic deformations. More generally spoken, NOGRID points software considers all the viscous as well as elastic/plastic stress tensors and any mixture of it.
NOGRID points software does not require a grid or mesh, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, where the generation of meshes takes a long time. NOGRID points can excellently be applied in case of all problems, where gridbased methods reach their limits due to the necessary remeshing. The software is based on one of the latest technologies in the area of numerical flow simulation. Using the fast and robust NOGRID points solver the usual long modeling and computing times can be shortened substantially.
Advantages are:

Here some examples for using NOGRID points:
 Fluid dynamical problems with free surfaces
 Moving parts
 Multiphase flows
 Fluidstructure interactions with a strong change of the computing domain
 Mechanical problems with substantial structure changes
The basis of the computations is a point cloud, which represents the continuum or in other words a continuum domain (fluid or solid) is replaced by a discrete number of points, which are referred to as finite points. Each finite point carries all fluid information, like density, velocity, pressure, temperature. Finite points can move with fluid velocity (Lagrangian approach) or the flow information runs through the finite points if they are located constant in space (Eulerian approach). Also a mixture approach (Arbitrary Lagrangian Eulerian ALE) is possible. This is useful in case of using the Eulerian approach in combination with free surfaces or moving parts. Therefore, finite points themselves can be considered as geometrical grids of the fluid domain.
