My ideia is to have those coordinates displayed in a. Second, it allows access to certain element results data that are not otherwise directly accessible, such as derived data for structural line elements. The element is defined by 20 nodes having three degrees of freedom per node: translations in the nodal x, y, and z directions. There is a coordinate system for the node, a coordinate system for its parent, one for its parent, and so on, and eventually a coordinate system for the Scene and one for the screen (which is potentially a collection of physical display devices). When using contact elements in. Users familiar with the way ANSYS numbers nodes will realize that node 1 will be on the far left, as it is keypoint 1, node 2 will be on the far right (keypoint 2), and the rest of the nodes are numbered sequentially from left to right. This reduces the required computation time and also allows the solution of very large problems. No matter when you defined the node rotation, the directions of the forces applied on the rotated nodes will change to local axis. NASA Technical Reports Server (NTRS) Papell, S.
