mymesh.utils.CalcFaceNormal# mymesh.utils.CalcFaceNormal(NodeCoords, SurfConn)[source]# Calculates normal vectors on the faces of a triangular surface mesh. Assumes triangles are in counter-clockwise when viewed from the outside Parameters: NodeCoords (list) – List of nodal coordinates. SurfConn (list) – Nodal connectivity list of a triangular surface mesh. Returns: List of element surface normals . Return type: ElemNormals list
