ANSA is a computer-aided engineering tool for finite element analysis and computational fluid dynamics analysis widely used in the automotive industry. It is developed by BETA CAE Systems. The software is distributed world wide by a number of BETA CAE Systems subsidiaries and business agents. In the United States, it is distributed by Beta CAE Systems, USA, based in Farmington Hills, Michigan.
ANSA maintains the association between computer-aided engineering geometry and the finite element mesh.[citation needed] This means that the finite element meshes are better representations of their geometric parents.[citation needed] Also it is easy to maintain and update any changes in the geometry by simply reworking the updated area instead of recreating the finite element from scratch.[according to whom?]
It carries several proprietary algorithms for meshing suitable for both CFD and structural models.[citation needed] ANSA initially stood for 'automatic net generation for structural analysis', but the software has gone beyond that very quickly.[citation needed]
