CFD SIMULATION & ANALYSIS

Problem solving through advanced
CFD simulations

The use of advanced computer systems has changed engineering substantially and is now indispensable. Within the framework of CAE (Computer-Aided Engineering), it is CFD (Computational Fluid Dynamics) which enables the modeling of heat transfer and complex fluxes in defined areas. It describes the segmentation of a considered volume into multiple cells of a very small size and the numerical calculation of the cells’ properties and its local flux conditions.
Such simulations of the conditions in the entire area provide valid and accurate approximations of reality. The main constraint of the technology is the available computational power due to the calculations’ high demands in this regard.
