26 April 2020 04:59:16 PM TET_MESH_L2Q C++ version Read a "linear" tet mesh and write out a "quadratic" one. Read a node file of NODE_NUM1 nodes in 3 dimensions. Read an associated tet mesh of TETRA_NUM tetrahedrons, using 4 nodes per tetrahedron. Create new nodes which are midpoints of sides, generate new node and tet mesh data for quadratic 10-node tetrahedrons, and write them out. Compiled on Apr 26 2020 at 16:54:42. Read the header of "mesh_nodes.txt". Spatial dimension = 3 Number of nodes = 8 Read the data in "mesh_nodes.txt". First 5 nodes: 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 "mesh_elements.txt". Tetrahedron order = 4 Number of tetras = 6 Read the data in "mesh_elements.txt". First 5 tetrahedrons: 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 TET_MESH_BASE_ZERO: The element indexing appears to be 1-based! This will be converted to 0-based. Number of quadratic nodes = 27 First 5 quadratic nodes: 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 First 5 quadratic tetras Row: 1 2 3 4 5 6 7 8 9 10 Col 1 3 2 4 0 15 18 10 16 9 11 2 3 1 4 0 12 18 10 13 8 11 3 3 6 2 4 20 15 18 17 23 16 4 3 6 7 4 20 21 18 26 23 24 5 3 5 1 4 19 12 18 14 22 13 Wrote the file "mesh_l2q_nodes.txt". Wrote the file "mesh_l2q_elements.txt". TET_MESH_L2Q: Normal end of execution. 26 April 2020 04:59:16 PM
