Description

If you are an application engineer who applies CFD using commercial software to solve engineering problems, then this course will be of great help to move to OpenFOAM ®.

OpenFOAM® today is 2nd most widely used CFD package in the world, is completely free and highly customizable due to availability of source code.

This training is delivered by ESI's CFD services team which has rich experience of over 20 years. Trainers will also share their experience of handling various projects which is unmatched with any other training that is being offered around.

OpenFOAM® Version:

OpenFOAM v1812 will be used for this training.

Training Cost:

INR 10,000 + taxes

Audience

CFD Engineers / Managers / Analysts [Indian Nationals]

Objectives

The main emphasis of this training is hands-on, users will be executing the tutorials along with the trainer right from the first hour of the training. This will enable users to have a feel of the software in applying it to solve the daily engineering CFD problems.

Prerequisites

Prior experience with a CFD is recommended but not required.
