**NOGRID points** software, based on the Finite Pointset Method (FPM), is a Computational Fluid Dynamics (CFD) software package for simulation tasks in a wide area of flow and continuum mechanical problems. FPM is a method for the solution of the equations governing viscous fluid flows, including the effects of heat and mass transfer. NOGRID points software models problems in continuum mechanics. The method solves not 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 is based on FPM as a grid-free method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, it does not require a grid or mesh. NOGRIDs flow simulation software is one of the latest technologies in the area of numerical flow simulation. Classical numerical methods (such as Finite Elements or Finite Volumes) need a grid or mesh for simulation. The generation of mesh takes a long time. Our NOGRID points-CFD (Computational Fluid Dynamics)-software is a grid-free (or meshless) method which, in contrast to classical numerical methods, such as Finite Elements or Finite Volumes, does not require a grid or mesh. The 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.

Nogrid points 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.

Simulation, especially fluid flow simulation or CFD (Computational Fluid Dynamics) is not usually easy to operate and companies commonly need CFD experts to compute such tasks. To overcome this sticky situation, in the last two years Nogrid has developed a forming simulation software especially for the glass container industry. The name of the software is **NOGRID pointsBlow** and the software computes the glass container forming process in full 3D. NOGRID pointsBlow software allows simulating all three kinds of container glass forming processes: BB (Blow and Blow), PB (Press and Blow or Wide Mouth PB) and NNPB (Narrow Neck Press and Blow).
