17 September 2021 11:54:34.466 PM TRIANGULATION_L2Q FORTRAN90 version Read a "linear" T3 triangulation and write out a "quadratic" T6 triangulation. Read a dataset of NODE_NUM1 points in 2 dimensions. Read an associated triangulation dataset of ELEMENT_NUM triangles which uses 3 nodes per element. Create new nodes which are triangle midpoints, generate new node and triangulation data for quadratic 6-node elements, and write them out. Read the header of "example_nodes.txt". Spatial dimension DIM_NUM = 2 Number of points NODE_NUM_T3 = 20 Read the data in "example_nodes.txt". 5 by 5 portion of data read from file: Row 1 2 Col 1: 0.00000 0.00000 2: 1.00000 0.00000 3: 2.00000 0.00000 4: 3.00000 0.00000 5: 4.00000 0.00000 Read the header of "example_elements.txt".
