I am starting a new series of tutorials about Gmsh today and start from scratch to teach about one of the most (in)famous open source pre-post software: Gmsh!
Whatever your CAE engineering background, you have some high chances to meet Gmsh at least once in your career and while it can be easy to use if you just know a few basic commands, it can also be hard and unsettling if you have never used it (especially the Gui which is quite unusual in my opinion).
Also, it’s a French software so I guess I was meant to present it to you one day or another ;-)
What is Gmsh?
Gmsh is an open source 3D finite element mesh generator with a built-in CAD engine and post-processor. Its design goal is to provide a fast, light and user-friendly meshing tool with parametric input and advanced visualization capabilities. Gmsh is built around four modules: geometry, mesh, solver and post-processing.

If you like these videos about Gmsh, Please consider giving a like to the video and leaving a comment, I read all of them.
Thanks for reading as always and Have fun with Gmsh!

Hey Cyprien,
Thanks for the nice tutorial, I discovered GMSH a few months ago and this is really a great, relatively intuitive tool. Do you plan to cover GetDP / ONELAB / conveks after the tutorials on GMSH?
Best,

Dear Sir,
I hope this message finds you in good health. I like the way that you teach. My name is Babar Hussain Shah, and I am currently pursuing a Ph.D. in the field of heat transfer analysis using theoretical methods. In my quest to expand the scope of my research, I have been exploring the possibility of comparing my theoretical findings with those obtained through Computational Fluid Dynamics. To accomplish this, I have been working with T-flow code and Gmash for geometry creation. However, I have encountered a significant challenge in creating a von-Karman surface that resembles an F-16 fighter jet nose cone.
I am writing to inquire if you could offer any guidance or perhaps provide a tutorial lecture on how to create this specific geometry. I am willing to provide the function of this particular geometry to aid in obtaining the necessary points. Any assistance you could offer would be greatly appreciated.
Function
r_o (x)=L/√π √(θ-sin(2θ)/2+C〖sin〗^3 θ),θ=cos^(-1)(1-2x/L); C=0,
Thank you for your time.
Sincerely,
Babar Hussain Shah
