Spent four days in figuring out how to construct an OpenFOAM polyMesh manually, it is more complicated than I thought, the difficult part is how to construct a multi-block mesh. One of the annoying issues in a multi-block polymesh construction is how to handle its internal lines/surfaces, where two lines become one. And then the points indices and the face indices all have to change accordingly. There may be many approaches to address this, but I, after many days' thought, decided to use a brutal...

Trust me, I've read more than 20 structured mesh generator codes already in the last year. Interestingly, none of them satisfy me. So I decided to make it my own. I've been working on this small mesh generator for quite a while. It worked before for a single block mesh smoothing. But starting from last month, as I was thinking about how to make it "multi-block", I decided to rewrite the whole code. Because it is quite different from C++ point of view to design classes for a single block...
