The aim of numerical fluid mechanics is to solve fluid mechanics problems approximatively with numerical methods.
Computational Fluid Dynamics (CFD) also covers the adjoining areas of thermodynamics, heat and mass transfer, thermal stress analyses, chemical reactions, etc.

Due to increasing computing capacity and continuous development of numerical models and algorithms, the field of CFD has become of outstanding importance for the simulation of flows in recent decades. On the one hand, numerical flow simulation enables a reduction of costly experimental analyses and on the other hand, flow phenomena are better understood than previously possible on the basis of measurements.
