29 April 2020 08:00:59 AM TET_MESH_QUALITY C++ version Compute tet mesh quality measures. Compiled on Apr 29 2020 at 08:00:55. Read the header of "cube_nodes.txt". Spatial dimension DIM_NUM = 3 Number of points NODE_NUM = 8 Read the data in "cube_nodes.txt". 5 by 5 portion of data read from file: Row: 1 2 3 Col 1 0 0 0 2 0 0 1 3 0 1 0 4 0 1 1 5 1 0 0 Read the header of "cube_elements.txt". Element order = 4 Number of elements = 6 Read the data in "cube_elements.txt". Portion of ELEMENT_NODE: Row: 1 2 3 4 Col 1 4 3 5 1 2 4 2 5 1 3 4 7 3 5 4 4 7 8 5 5 4 6 2 5 6 4 6 8 5 TET_MESH_BASE_ZERO: The element indexing appears to be 1-based! This will be converted to 0-based. Minimum Mean Maximum Variance Quality measure 1 = 0.717439 0.717439 0.717439 1.47911e-32 Quality measure 2 = 0.585786 0.585786 0.585786 0 Quality measure 3 = 0.755953 0.755953 0.755953 1.47911e-32 Quality measure 4 = 0.479584 0.479584 0.479584 0 Quality measure 5 = 1 1 1 0 Here is a numerical histogram of the order of each node in the mesh, that is, the number of tetrahedrons that include that node as a vertex. For a regular mesh, most nodes would have the same order. Order Number of Nodes 2 6 6 2 TET_MESH_QUALITY: Normal end of execution. 29 April 2020 08:00:59 AM
