NOGRID POINTS - MESHLESS CFD SOFTWARE
NOGRID points is a general-purpose Computational Fluid Dynamics (CFD) software package based on a meshless method. It is designed to simulate a broad range of flow and continuum mechanics problems, including fluid dynamics as well as elastic and plastic deformation. The software can handle all types of stress tensors - viscous, elastic, plastic, or any combination thereof - making it a powerful tool for complex multi-physics simulations.
No time consuming mesh generation necessary
Unlike traditional CFD methods such as Finite Element or Finite Volume techniques, NOGRID points CFD software does not require any grid or mesh. Mesh generation in conventional solvers is often time-consuming and costly. With NOGRID's meshless CFD software, these complex and resource-intensive meshing steps are eliminated, resulting in faster setup times and reduced engineering costs.
NOGRID points is particularly effective in scenarios where conventional mesh-based approaches struggle - especially when frequent remeshing is required due to moving boundaries or complex geometries. Thanks to its fully meshless architecture, NOGRID points delivers robust and accurate simulation results.
Outstandingly short modeling and computing times
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 commonly long modeling and computing times can be significantly reduced.
Advantages of meshless CFD simulation with NOGRID points CFD software:
- Extremely short modeling time due to the absence of meshes
- Dramatically reduced computing time in case of free surface flows or flows with moving parts or moving boundaries
- Direct import of models from other CAD systems by IGES/STEP interface
- Easy modeling of all free surface problems
- Easy modeling of moving parts in your flow domain
NOGRID points meshless CFD software is an amazing strong and powerful simulation tool for:
- Fluid dynamical problems with free surfaces
- Moving parts
- Multiphase flows
- Fluid-structure interactions with a strong change of the computation domain
- Mechanical problems with substantial structure changes
Point cloud instead of mesh
The basis of the computations is a point cloud that 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, and temperature. Finite points can either move with the fluid velocity (Lagrangian approach), or the finite points remain fixed in space while the flow information runs through them (Eulerian approach). Also a hybrid Arbitrary Lagrangian Eulerian (ALE) approach is possible. This is useful in case of combining the Eulerian approach with free surfaces or moving parts. In this context, finite points themselves can be considered as geometrical grids of the fluid domain.
