I don’t have experience in developing large projects. What I know about writing C++ is to create a .cpp file in visual studio in windows, include appropriate header files, write the main function, and then build the solution. Since I saw that FreeFem is written in C++, I thought I can use it as other libraries, like #include. However, I can’t find the related instructions and examples about configuring with Visual Studio, like what directories should be included in the project, and what is the simplest .cpp file for testing the configuration. Please let me know if you know of any tutorial on the configuration with VS. Thanks a lot.
