[ANSYS Meshing] Determine the cell order in the face definition

dynlevirus · August 27, 2012, 08:11

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
