7 Reasons why NOGRID Customers are using Simulation
Computational fluid dynamics (CFD) is the discipline of science devoted to predicting fluid flow, heat transfer, mass transfer, chemical reactions, and related phenomena by solving the mathematical models that govern these processes using a numerical process. CFD is becoming an increasingly important design tool in engineering and also a substantial research tool in certain physical sciences. Due to the advances in numerical solution methods and computer technology, geometrically complex cases can be treated.

NOGRID software is a most modern technology based on a meshless method to solve the Navier-Stokes equations. It 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.
By using these new techniques, designers can verify that their products will comply with customer’s specifications early in the design cycle. So, the product development process will be accelerated and the cost will be reduced by avoiding production trials. CFD can be used to compute material properties, heat transfer rates and chemical reactions during the process and for the final product. Those advantages are very important and have helped engineers to obtain insight in problems where analytical solutions are impossible and/or experimental measurements are too difficult or too expensive to obtain.

NOGRID develops new numerical tools and software to allow our customers to accurately and efficiently model complex systems and to study the behavior of liquids and solids over a variety of length scales and applications.
CFD modeling is almost always faster than physical modeling or performing production trials. In many cases, design results from a CFD model are available several weeks or months before similar results from experiment. And the more complicated or repetitive the model geometry is, the more advantage the CFD model has. Once a CFD model is built, it can be run simultaneously on separate computers. Thus, several designs can be evaluated at the same time, while only one real design exists for evaluation. CFD model studies are generally 30-70% less than a comparable experimental effort, especially if a CFD model is already existing. This is tied quite strongly to the product and the production process that influences the schedule. Also, many CFD tasks can be automated with the computer, including the design optimization process, whereas experiments or real design changes are primarily manual.
