NASCRITFRM,<file>,<FN>,<V>,<STR>

This command find the absolute maximum of a single time history and stores the information in variables for later use. The results of each NASCRITFRM command is appended to the three variables, so using NASCRITFRM on multiple files with the same variables will build up a data set that can be written to a single file using NASCRITRPT or be used by FRMTXTSEL to generated critical frames for plotting. When using the FRMTXTSEL command only the data from variable <V> should be used to generate the “*_rdi.frm” file. In stress time histories positive or negative values are used to determine the direction of the stress, therefore absolute value is used when determining the maximum critical value stored in <STR> variable. However, the critical value will be stored in the <STR> variable with it signed value from the time history.

• file - filename of the time history being processed
• FN - Variable name storing a list of filenames that have already been processed. This Variable is intended to be used with the NASCRITRPT command.
• V - Variable name storing a list Step number where the absolute maximum is found
• STR - actual value of the maximum. This Variable is intended to be used with the NASCRITRPT command
