How to create my own simulation without modifying the existing example codes?

[LeSnow-Ye]

I'd like to use MFEM to do a simple simulation. But I'm new in C++, and I'm having touble including MFEM in another project. Is there a tutorial for using MFEM outside its source code or adding my own "miniapp" or .cpp file under the examples folder ?

You can examine the makefiles in the miniapps directories, which are essentially external apps.

If you just want to add a new example-like file, say my.cpp, you can simply put it in the examples/ directory and should be able to build it with make my.

I found this repo a few days ago. By referencing its CMakeLists.txt and using cmake .. -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH=/path-to/mfem/, I managed to get things done. Also, I'm using cmake to build MFEM following HowTo/build-systems. I haven't tried using make to build MFEM for external projects in this way.
