Jet Towers used ANSYS AIM simulation software to design a line of truss tower modules that makes it possible for the company to build and install wireless towers in only one week, one-fifth the time required by conventional methods. While this type of bridge is easy to construct, engineers must make sure that it lasts and is safe to use. 1 Local and Global Coordinates We start by looking at the beam or element shown in the diagram below. Ansys allows you to insert APDL commands using this command feature, however some commands are limited in Workbench; there is much you cannot do in Workbench. By definition, the truss elements have pinned joints, so you do not have to worry about modelling each of the defined joints. Guidelines for successful FEA 3-6 4.
