07-Jan-2022 20:05:07 fem_io_test(): MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2 Test fem_io(). FEM_IO_TEST01 FEM_READ reads finite element data from files. The node coordinate file name is "ell_nodes.txt". The element file name is "ell_elements.txt". The node data file name is "ell_values.txt". The number of nodes in the node coordinate file is 2. but the number in the node data file is 1 Because of this, no node data will be stored. Spatial dimension = 65 Number of nodes = 2 Element order = 96 Number of elements = 3 Number of node data items = 0 First 10 node coordindates: Row: 1 2 3 4 5 Col 1: 0 0 0.5 0 0.5 2: 0 0.5 0 1 0.5 Row: 6 7 8 9 10 Col 1: 1 0 0.5 1 1.5 2: 0 1.5 1 0.5 0 Row: 11 12 13 14 15 Col 1: 0 2 1.5 1 0.5 2: 4 4 4 4 4 Row: 16 17 18 19 20 Col 1: 0 0 0 0 0.5 2: 3.5 3 2.5 2 1.5 Row: 21 22 23 24 25 Col 1: 1 1.5 2 0.5 2 2: 1 0.5 0 3.5 3.5 Row: 26 27 28 29 30 Col 1: 1.5 1 0.5 0.5 0.5 2: 3.5 3.5 3 2.5 2 Row: 31 32 33 34 35 Col 1: 1 1.5 2 2.5 1 2: 1.5 1 0.5 0 3 Row: 36 37 38 39 40 Col 1: 2 1.5 1 1 1.5 2: 3 3 2.5 2 1.5 Row: 41 42 43 44 45 Col 1: 2 2.5 3 1.5 2 2: 1 0.5 0 2.5 2.5 Row: 46 47 48 49 50 Col 1: 1.5 3.5 2 2.5 3 2: 2 0 1.5 1 0.5 Row: 51 52 53 54 55 Col 1: 4 2 3.5 2.5 3 2: 0 2 0.5 1.5 1 Row: 56 57 58 59 60 Col 1: 4 2.5 3.5 3 4 2: 0.5 2 1 1.5 1 Row: 61 62 63 64 65 Col 1: 3 3.5 4 3.5 4 2: 2 1.5 1.5 2 2 First 10 elements Row: 1 2 3 4 5 6 7 8 9 10 Col 1: 1 6 4 3 23 21 6 22 19 4 2: 3 5 2 5 22 9 10 9 7 8 3: 2 3 5 2 10 22 9 10 20 7 Row: 11 12 13 14 15 16 17 18 19 20 Col 1: 21 7 6 21 4 9 52 39 41 46 2: 20 8 9 8 5 8 46 40 48 40 3: 8 20 5 9 8 5 48 46 40 48 Row: 21 22 23 24 25 26 27 28 29 30 Col 1: 19 21 39 20 23 41 21 33 39 21 2: 20 31 30 31 33 32 22 32 31 32 3: 30 20 31 30 22 33 32 22 40 31 Row: 31 32 33 34 35 36 37 38 39 40 Col 1: 41 31 23 43 41 34 51 55 43 53 2: 40 32 34 42 33 42 53 50 47 50 3: 32 40 33 34 42 33 47 53 50 47 Row: 41 42 43 44 45 46 47 48 49 50 Col 1: 52 41 55 48 43 55 41 50 65 61 2: 48 49 54 49 50 49 42 49 64 62 3: 54 48 49 54 42 50 49 42 63 64 Row: 51 52 53 54 55 56 57 58 59 60 Col 1: 60 64 52 55 61 54 51 60 55 56 2: 63 62 54 59 57 59 56 58 53 58 3: 62 63 57 54 59 57 53 56 58 53 Row: 61 62 63 64 65 66 67 68 69 70 Col 1: 61 55 60 59 19 39 17 30 52 35 2: 59 58 62 58 30 29 18 29 44 38 3: 62 59 58 62 18 30 29 18 46 44 Row: 71 72 73 74 75 76 77 78 79 80 Col 1: 39 44 11 17 35 16 39 35 17 38 2: 46 38 16 28 24 28 38 28 29 28 3: 38 46 24 16 28 24 29 38 28 29 Row: 81 82 83 84 85 86 87 88 89 90 Col 1: 12 14 36 13 11 35 14 24 52 36 2: 13 26 25 26 24 27 15 27 45 37 3: 25 13 26 25 15 24 27 15 44 45 Row: 91 92 93 94 95 96 Col 1: 35 45 14 35 36 27 2: 44 37 27 37 26 37 3: 37 44 26 27 37 26 First 10 node data sets: (None) FEM_IO_TEST02 Demonstrate the use of FEM_WRITE to write finite element data to files.
