Determine the cell order in the face definition
Hi All,
I'm trying to figure out how the mesh is constructed in the Fluent format (.msh).
In the Fluent User's guide, the describe all of it. Nevertheless, I can't figure out the order of the cell o construct a face. In Fluent user's guide B.3.7 Faces, they say: "
The order of the cell indices is important, and is determined by the right-hand rule: if you curl the fingers of your right hand in the order of the nodes, your thumb will point toward c1. "
Someone does understand this?

Here, let me google that for you...

Perhaps it would help to display the node numbers? Then it may become clear.

Thank for your answer.
Indeed, I undertand the rule of the right hand rule. I can apply it to a simple mesh since I write it by myself but for a bigger mesh it becomes quite impossible
