Identify the commands required to be present in an ANSYS input file for use with Simulation Composite Analysis.
These commands ensure complete compatibility with Simulation Composite Analysis and are necessary to take full advantage of its superior convergence characteristics for nonlinear, progressive failure problems. More specifically, this section explains the need for these commands in terms of the unique characteristics of Simulation Composite Analysis. This section does not discuss the formatting requirements of any individual command, nor does it discuss any of the specific options or data of any individual command; these issues will be covered later (Use ANSYS APDL to Create Input Files and Use a Text Editor to Convert ANSYS Input Files).
