Greetings to all redditors in this sub!

A few years back I stumbled upon Construct2D, a solid mesher for 2D airfoils.

The original Construct2D source code is still available here:
https://sourceforge.net/projects/construct2d/

Construct2D creates good quality meshes and is simple and intuitive to use.
However, as I kept using it, I found that it lacked some functionality. For example, I would've liked more output formats that can be loaded and converted easily to other formats. Plot3D only goes so far.

In addition, boundary conditions were also important. I didn't want to always have to redefine boundaries in different formats.

Finally, at least to my knowledge, Construct2D is not actively maintained. The latest source code is from 2018. I was not able to find anything newer online, nor did I find a github or gitlab repository.

Therefore, I decided to modify it and add more output format options and I also implemented some additional features like multigrid output and swept-wing extrusion.

I figured I'd upload it to GitLab and try to improve it further down the road.

It is available here:
https://gitlab.com/before_may/structAirfoilMesher

I did my best to document it and provide instructions, although documentation is by no means perfect yet.

Compilation is very straightforward on Linux or WSL; you can build it using GNU/Intel/NVIDIA compilers. Just load your compiler environment and use make to build what you want. No Makefile editing needed.

For CGNS output, building the CGNS library is required. I have included automated scripts to download, build, and link the library.

I have tested it on a couple systems, everything seems to work.

For OpenFOAM users, I have a dedicated instruction file that lists and describes available options that can help you convert to OpenFOAM format.

Give it a shot and tell me what you think! I hope you'll find it useful.

I have plans to continue development, there are a couple things that can be added easily and handful others that require more work.

Contributions and ideas are welcome!
