If you want to stop your current Ansys Polydata session and continue it another time (that is, if your problem definition is incomplete, so you cannot save a data file), you can save the current session data to a file by clicking the SAVE button at the top of the Ansys Polydata menu. The resulting file will contain a subset of the information in a complete data file, as discussed in Contents of the Data File.

You can restart Ansys Polydata later and read in this file (using the Read an old data file menu item, as described in Reading a Data File into Ansys Polydata) to continue your session. Note that you cannot read the session file into Ansys Polyflow. The data file (see Reading and Writing Ansys Polydata Data Files) is the way to transfer your problem definition to Ansys Polyflow to calculate a solution.
