The tagging of inputs for Ansys Polydata is discussed below. The tagging of the inputs for an external program is left up to you.
In Ansys Polydata, the inputs are tagged using the button. When you click , a menu is displayed that allows you to create an entry for a template for a particular parameter. During optimization, Ansys Polydata writes a tag and its value to the input file for the parameter. The input file is used by VisualDOC for the replacement of inputs.
