# CFD Simulation with ANSYS FLUENT

In today’s competitive world, simulation has become an important tool for design and operation control. It helps to find the quick and accurate results throughout design and manufacturing as well as during end use. ANSYS FLUENT software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants. This simulation software allows you to predict, with confidence, the impact of fluid flows and heat transfer on your product.

This course explicitly focuses on solver and post-processing part of typical CFD process using simulation tool ANSYS FLUENT. This course is a perfect blend of theoretical foundation and software exposure. This course starts with the CFD fundamentals. Under which you will be learning partial differential NS equations, numerical methods, and finite volume method. Once you are comfortable with the basics of CFD, you will learn the solver ANSYS FLUENT software. Primarily you will get acquainted with the GUI of software.
