Ask for help with C++ compilation

[passenger]

I downloaded the source code of the OS and compiled it by calling the relevant files. As a newbie, I had a hard time finding effective learning resources and wondering if anyone would be willing to recommend tutorials.
Specifically, the problems I am encountering now are:
1. How to achieve meshing for board elements. (I used the plate element created by ShellMITC4 and meshed it by building many small elements, but the calculation was obviously wrong)
2.I don't know how to quickly find the function I'm going to use. For example, what function should be used to create a board unit, I looked at a lot of header files before I chose to try the ShellMITC4 function. Now I want to build beams and columns, and I don't know what function to use.
I hope someone can help me, and I would be very grateful
