These options include the maximum number of restart files that you want ANSYS to write for a load step as well as how frequently you want the files to be written. For an overview of the Solution Controls dialog box see Using Special Solution Controls for Certain Types of Structural Analyses p. 108 . For details about how to set options on the Solution Controls dialog box access the dialog box Main Menu Solution Sol n Control select the tab that you are interested in and click the Help button. . Multiframe Restart Requirements The following files are necessary to do a multiframe restart Jobname . RDB - This is an ANSYS database file saved automatically at the first iteration of the first load step first substep of a job. This file provides a complete description of the solution with all initial conditions and will remain unchanged regardless of how many restarts are done for a particular job. When running a job you should input all information needed for the solution - including parameters
