I wrote a Matlab code to create mesh structure. My mesh is quadrilateral surface mesh for vascular. I create a mesh structure based on the following document. However, when I create simple tubular surface mesh with CFX .msh format is completely different in terms of faces. I want to know which one is actually .msh file and which rule is the one that I should pursue.
Thank you.

in the PDF the format: each face is connecting two points and two other indices will be used to show the right and left side cell index that the face is connecting.

(13 (2 1 2 2 2)(
1 2 1 2 % Here two first columns are points index &two other one cell indices
3 4 2 3))

However, in the ANSYS CFX forth first column are point indices and two other (zeros) are cell indices which are zeros because of surface mesh.
