2 Range of Technologies ANSYS Software provides a comprehensive range of simulation technologies: Computational Fluid Dynamics (CFD) Finite Element Analysis (FEA) Implicit (low speed) Explicit (high speed impact/blast) Electromagnetics Low frequency (Motors / Transformers) High frequency (Microwave / Signal Integrity) 2011 ANSYS, Inc. All rights reserved. 2 ANSYS, Inc. Proprietary
3 Modelling Approach CFD and FEA models offer reliable, validated techniques for simulating how fluids and structures behave The underlying technology is very similar: A CAD model of the part is made, Control Volume This is decomposed into a large number of component grid cells, or elements The governing equations of fluid or structural mechanics are then solved at each of these grid locations (usually in an iterative manner). Combined, this provides a detailed 3D picture of how the part responds to the loads / flow conditions involved Finite Element 2011 ANSYS, Inc. All rights reserved. 3 ANSYS, Inc. Proprietary
