19. on MAXMIN Find Maximum and Minimum Element Stress Levels 1 Introduction The MAXMIN program permits users to access the stress output files from ASAS or the identically formatted files from LOCO and determine the maximum and minimum stress levels in the structure for those loadcases reguested by the user which may be a subset of the total loadcases in the ASAS or LOCO analysis The facility exists to save the backing file used by MAXMIN for further use The user can output a selected subset of the elements within the structure or select given groups to be output Additionally the user can compare successive runs on a structure by reading the stress file for the later analysis and comparing the values with the MAXMIN filed values from a preceding analysis Included within this is the feature to do fail safe comparison analyses If an initial run is conducted with a complete structure and a MAXMIN file produced then the subseguent comparison runs may have elements omitted If this option is exercised then the structure and defective derivatives thereof must have unigue user element numbers defined in the element topology data of the ASAS analyses There is no theoretical restriction on the number of times MAXMIN may be run on a structure or its derivatives An example of the possibilities is shown in Figure 1 Another user option included is the ability to produce output for the axial elements with either the overall ele
