The function femTriangularMeshGenerator() generates triangular mesh for a rectangular shape structure for Finite Element analysis. The outputs are: coords = x and y coordinates of each element nodes cT = nodal connectivity nNodes = Number of nodes The inputs are: Lx = width of the rectangular structure Ly = Height of the rectangular structure Nx = Number of divisions on x- axis NE = Number of elements The example generates 144 elements for a rectangular structure given a dimension 10units by 10units with respect to 8 divisions on x-axis.
