Issue I351 [80,enhancement,resolved] In main screen, non-refined PAs are now marked with "!". Description: Starting in 8.0.2, potential arrays that are determined to be unrefined (or are PA# files that are not solution arrays) are marked with '!' in the PA list on the main screen. This is mostly as a safeguard/warning for users, especially new users. The criteria used to determine whether a potential array is unrefined is not precisely defined (it depends on what you consider an acceptable level of convergence). So, a potential array not marked with '!' may still need to be refined. For purposes here, the criteria used by SIMION to determine if a PA should be considered unrefined is basically as follows. A .PA file is considered unrefined if the maximum refine convergence level in the .PA is above 0.01 times the maximum span of voltages in the .PA. Determining that error requires basically that SIMION do a single refine iteration that only computes the maximum error (but does not modify the .PA). A .PA file will also be considered unrefined if you modify it but don't subsequently re-refine it. Fast adjusting does not alter the refine status. .PA0 files (as well as .PA[1..n_] file) are normally always considered refined, even if the corresponding .PA# file is edited. However, if you edit one of these files directly (which you normally should not do), the file will be considered unrefined. .PA# files are themselves normally always considered unrefined, even if the corresponding .PA0 file exists. Update: 8.0.4-TEST12 Display meaning of [!] and [*] as tooltips in statusbar. Resolved in 8.0.2.
