'''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 worldwide 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.{{cn|date=February 2023}}<ref name=":0">{{Cite web |last1=Tsouknidas |first1=A |last2=Savvakis |first2=S |last3=Michailidis |first3=N |last4=Anagnostidis |first4=K |title=ANSA AS AN ADVANCED TOOL IN BIOMEDICAL MODELLING AND ENGINEERING |url=https://www.beta-cae.com/events/c4pdf/8A_3_tsouknidas.pdf}}</ref> This means that the finite element meshes are better representations of their geometric parents.<ref name=":0" /> 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.<ref name=":0" />

It carries several proprietary algorithms for meshing suitable for both CFD and structural models.{{cn|date=February 2023}} ANSA initially stood for 'automatic net generation for structural analysis', but the software has gone beyond that very quickly.{{cn|date=February 2023}}
