coding problem
 

Hi guys, right now I am reading the openfoam's code and wonder what the meaing of "tetFaceI and tetPtI " in openfoam, this bothers me a lot and I konw "I" should be the index i, but I don't know what the tetFace and tetPt mean.
Thanks!

You should specify where you have found these words! Just from guessing, it is hard to give you a right answer. But if I should guess, I would say the whole word is just the index in a loop :rolleyes:

Thansk for answering. The tetFaceI and tetPtI actually first comes out in the lagrangian/basic/particle/particle.H. Yes, they are indexes. The thing I don't get actually is I don't know where do we get the tetrahedron? I mean in the particle.H profile it states "the decomposed tet". So is the tetrahedron divided from a cube defined in openfoam? I don't konw the tetrahedron part totally..
