General description

NUMECA International is a leading developer and provider of CFD software systems for the multi-physics design simulation and optimization of industrial products and processes.  Its software products are used for the simulation of fluids, acoustics and thermal systems in a large range of applications.

NUMECA software are being used in the design phase process of a large number of industries worldwide, and in particular in the aerospace, turbomachinery, energy, marine, combustion and automotive markets.

NUMECA counts around 110 staff members, engineers and PhDs worldwide  and is present in most industrialized countries with branches in USA, Japan, China, India, Belgium and distributors in Germany, Spain, Italy, Korea, Indonesia…

As a spin-off of the Vrije Universiteit Brussels founded in 1993 by Prof. Charles Hirsch, NUMECA has a strong connection with universities and research centers worldwide and is partnering with the most dynamic and specialized academic groups worldwide.  NUMECA is active in many European and national R&D projects.
