OpenFOAM beginner core courses from Udemy

Computational Fluid Dynamics (CFD) is an advanced tools to solve complex fluid dynamic and heat transfer equations using numerical method. OpenFOAM is an open-source and free to use CFD solver with the largest community in the world. Despite its powerful capability, its major drawback is the step learning process. By making this course, I hope I can reduce the effort of new learners to start learning using this amazing and powerful tool.

In this course, you will get hands-on experience using OpenFOAM following the core theories related to the setting used in the simulation simply and intuitively, so you can use it for your applications.

You don't have to have basic LINUX or other programming experience before this course; we will explain some basic useful LINUX commands only related to the operation of OpenFOAM, and some efficient programming tricks will be also explained during the course.

This course will be separated into five parts (1) introduction, (2) core knowledge, (3) useful cases, (4) some advanced theories, and (5) More "realistic" applications.

with the focus on the basic "tutorial" case folder, meshing using blockMesh and snappyHexMesh, geometry editing using Blender, post-processing, turbulent modeling, scheme and algorithm theory, and some "real-world" workflow.
