Quad.py will crash with a runtimeError. it gets into a recursion loop trying to split a quadtree cell up with 14 verts in the same position, so it can't split the cell. The standard way we run ANUGA will not produce a vert connected to more than 13 triangles though. 14 triangles connected to one vert is a high ratio. If you have 13 triangles the average angle for the triangle corners is 27.7 deg. Meshes with min angles less than 28 deg cause problems with triangle. The default min angle is 28 deg.",defect,closed,lowest,,Functionality and features,,normal,fixed,,
