Before delving into the details of the procedures related to the ANSYS program, we define the following terms: Jobname: A specific name to be used for the files created during an ANSYS session. This name can be assigned either before or after starting the ANSYS program. Working Directory: A specific folder (directory) for ANSYS to store all of the files created during a session. It is possible to specify the Working Directory before or after starting ANSYS. Interactive Mode: This is the most common mode of interaction between the user and the ANSYS program. It involves activation of a platform called Graphical User Interface (GUI), which is composed of menus, dialog boxes, push-buttons, and different windows. Interactive Mode is the recommended mode for beginner ANSYS users as it provides an excellent platform for learning. It is also highly effective for postprocessing. Batch Mode: This is a method to use the ANSYS program without activating the GUI. It involves an Input File written in ANSYS Parametric Design Language (APDL), which allows the use of parameters and common programming features such as DO loops and IF statements. These capabilities make the Batch Mode a very powerful analysis tool.
