So the length is defined by modeling line while other dimension are defined by assigning respective cross sections to the line. Modeling: The shape of 1D element is line which is created by joining two nodes.Refer Figure 2, 1 st image shows 1D rectangular beam, in which length is very larger compare to height and width. In all this examples the length of the element is quite larger compare to width, height, or diameter. For example pipe, rod, bar, beams, axisymmetric shell etc. In case of 1D elements one of the dimensions is very large compare to other two dimensions. Refer Figure 1 for types of elements: Figure 1: Types of FEA Elements 1.Geometrical Dimension: 1D Element: ![]() These are mainly classified based on geometrical dimensions (1D, 2D & 3D), you can further add types based on element order, other or miscellaneous types. There are different types of finite elements.
