20 node brick element abaqus software

For the linear bricks c3d8s and c3d8hs in abaqus standard improved stress visualization is obtained through a 27point integration rule, consisting of 8 integration points at the elements nodes, 12 integration points on the elements edges, 6 integration points on the elements sides, and one integration point inside the element. In abaqus standard elements with midside nodes, such as the 20node brick shown in figure 2 b, use quadratic interpolation and are often called quadratic elements or secondorder elements. In abaqus standard elements with midside nodes, such as the 20node brick shown in figure 21. The node numbering follows the convention of figure 56 and the integration scheme is given in figure 57. Now mesh has been generated with four noded elements. Twentynode brick element c3d20 and f3d20 the c3d20 element is a general purpose quadratic brick element 3x3x3 integration points. Twenty node brick element with reduced integration c3d20r and f3d20r the c3d20r element is a general purpose quadratic brick element, with reduced integration 2x2x2 integration points. I habe written a code for shell elements which is as below fprintffid, %s\n, shell section, elsetlayupx1. The chimney is modeled as a cylindrical solid of steel and is created according to the geometric properties using a 20node quadratic brick element type. Abaqus automatically decides the best suited type of elements for the part. How the mortar and brick are modeled in abaqus using. How can i get outer nodes labels of the chimney that is.
