ANSYS ICEMCFD Hexa Basic course (Part 1)

Create high quality hexa meshes in ICEMCFD for accurate CFD simulation with 66 lectures and 12 comprehensive workshops
Instructor:
Sijal Ahmed
501 students enrolled
English [Auto]
Hexa mesh generation on 2d geometries for various examples

In this course students will learn basics of hexa meshing along with geometry operations and various other options in ICEMCFD. After going through lectures, we will apply this knowledge in 10 workshops which are designed to give you hand on practice on different commands and method in ICEMCFD.

Recently I have added two more workshops on hexa meshing of 2D turbine and compressor blades with periodic boundaries. Here you will learn about the complex application of multiple O-Grids (C-Grid, Quarter O-Grid etc) along with shifted periodic concept.

After going this course you will be able to understand hexa meshing concept, geometry operations etc and apply them on real world problems.

You can view and review the lecture materials indefinitely, like an on-demand channel.
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
