Hi all, I have a triangular mesh (facets) performed from the matlab function "tri". I export this facets on Gmsh via my Matlab routine in order to define a volume.
It seems that some facets are not correctly defined or well oriented because I cannot make my volume. I look at a simple geo file from Gmsh and I don't understand the principle or the logic to well oriented the facets. Usually, the facet is defined in relation to its normal vector (i.e., clockwise or counter-clockwise). >From the following figure, can you explain me how do I must define each facet >or triangle ? 3------6------9 | \ T2 | \ T4 | | \ | \ | | \ | \ | | T1 \ | T3 \ | 2------5------8 | \ T6 | \ T7 | | \ | \ | | \ | \ | | T5 \ | T8 \ | 1------4------7 1 - 2 - ... - 9 = nodes T1 - T2 - .... - T8 = triangles In matlab, each facet is defined in the counter-clockwise. In Gmsh, I didn't manage to define a rule. Please, can you give me more explanations on this subject ?
