Hello everyone!!
My domain is a cuboidal block and mesh consists of all hexahedral cells with a constant mesh size. I am using INTERIOR_FACE_GEOMETRY macro by looping over all the faces of all the cells(using c_face_loop) to get some outputs. I have some doubts about the outputs which we get from the macro INTERIOR_FACE_GEOMETRY. Though my domain is 3D, I have attached an image consisting of 3 square cells in 2D and nomenclature as per my understanding. Basically, I want some help regarding different names such as C0, C1, es, etc. in case of uniform mesh with hexahedral cells.
Please shed some light on whether my understanding is correct or not.
Thanks in advance.
