mymesh.quality.tri_area#
- mymesh.quality.tri_area(NodeCoords, NodeConn)[source]#
Element areas of a purely triangular mesh.
\[A = \frac{||(v_1 - v_0) \times (v_3 - v_0)||}{2}\]where \(v_0\), \(v_1\), and \(v_3\) are the coordinates \((x,y,z)\) of the vertices.
- Parameters:
NodeCoords (np.ndarray) – Node coordinates (shape=(n,3))
NodeConn (np.ndarray) – Node connectivity (shape=(m,3), dtype=int)
- Returns:
area – Areas of each triangle
- Return type:
np.ndarray
