Modal Analysis. GitHub Gist: instantly share code, notes, and snippets. COMBIN14 essentially offers two types of elements, selected with KEYOPT(2). Single DOF per node (KEYOPT(2) > 0). The orientation is defined by the value of KEYOPT(2) and the two nodes are usually coincident. I am trying to create a shaft with bearings and a force applied on the end. This is a rotating shaft for a spindle. For the bearing locations I want to place a spring in place of the bearings because there is a preload force with a corresponding stiffness value. I am reading online that COMBIN14 is used for what I am trying to accomplish. (COMBIN14 spring-damper element) were defined with 100 mm length on two sides as seen in FIGURE 7. The reader is recommended to read through related chapters of the PhD dissertation by Shen11 to obtain more detailed information about the non-reflected boundaries. FIGURE 8.
