Shape function in finite element analysis
Webb28 sep. 2024 · The basic shape function looks like, with the boundary condition on the left. At Ni=N1, x=x1, y=y1 (the coordinate of node 1), the shape function would be equal to 1, when Ni=N1, but x=x2,y=y2 (the coordinate of node 2), the shape function would be 0, and so on and similar at Ni=N2,N3 and such. WebbFunctions in finite element spaces ¶ Recall that the general form of a function in a finite element space is: (5.1) ¶ f ( x) = ∑ i f i ϕ i ( x) Where the ϕ i ( x) are now the global basis functions achieved by stitching together the local basis functions defined by …
