This course is full of best-in-class content by leading faculty and industry experts in the form of videos and projects

Course Overview

The students will gain a thorough knowledge of OpenFOAM Development.
During this coursework, the students are exposed to
- The fundamentals of developing CFD code in the framework provided by the open-source CFD toolbox.
- The fundamentals of C++, and the relevant mathematical constructs that will allow students to write their own CFD code within OpenFOAM.
The students are exposed to the modern trends and standard practices followed in the industry right now.
The course addresses the need to ascend the steep OpenFOAM learning curve quickly and effectively.

Our courses have been designed by industry experts to help students achieve their dream careers

Industry Projects

Our projects are designed by experts in the industry to reflect industry standards. By working through our projects, Learners will gain a practical understanding of what they will take on at a larger-scale in the industry. In total, there are 4 Projects that are available in this program.

Creating Scalar Form

In this project, you will create a solver using OpenFOAM. You will learn to customize it and its attributed cases.

Discretization Schemes

In this project, you will simulate cases such as diffusion and convection by varying the diffusion coefficient or velocity.

Creating icoTempFoam

In this project, you will add an equation of temperature in the icoFoam solver, customize it and its cases. You will be asked to solve the incompressible flow equations for mass and momentum.

Function Objects

The objective of this project is to calculate the total pressure using a coded function object. You will also write a short report including the code you used in LATEX.
