APPLICATION OF COMPUTATIONAL FLUID DYNAMICS IN REAL WORLD INDUTURY

PRESENTED BY: Dr. MOHAMMAD JADIDI

What are the important essential software a mechanical engineering

student should have some grip on?

Technical Computing MATLAB, Mathematica.

CATIA, SolidWorks, Pro-E, AutoCADCAD&CAM

Programming C++, Python, MATLAB

Computer-aided engineering (CAE) is the broad usage of computer software to

aid in engineering analysis tasks. It includes

Finite Element Analysis (FEA)

Computational Fluid Dynamics (CFD)

Multibody dynamics (MBD)

General MS-Office

CFD (computational fluid dynamics) is a set of numerical methods applied to obtainapproximate solutions of problems of fluid dynamics and heat transfer.
