cosin software 2024-4 release notes

General cosin software aspects

1. fix: potential crash in Windows with shorttir data file format
2. new internal function: automatic simplification of arithmetic expressions, results in accelerated evaluation

cosin graphical user interface (GUI)

1. launchpad simplified and window height reduced, to better fit on screens with poor resolution

FTire/core

1. fix: computation of reaction forces on moving contact bodies
2. fix: correct scaling of formula expressions in FTire data file when unit system is changed
3. make volume computation available in accelerated and RT mode
4. optional extra hysteresis added to bottoming part of radial stiffness characteristic

FTire/sim

1. new simulation script ‚drop tower‘
2. animation improvements

FTire/fit

1. fix: comparison of _best_so_far with other data file
2. fix: minor issue in simscripts cmp_vertlr_dyn.sim and cmp_vertlr_drum.sim

cosin/road

1. ’save as..‘ implemented

cosin/tools

1. added horizontal scrollbar to accommodate long path names
2. made sure new scrollbar in cosin/ip is only shown if needed
3. road generation for ISO 8608 road classes improved and made more accurate

cosin/tools for roads

1. fix: 2nd center-line creation
2. fix: misleading plot labelling in automatic visualization window
3. fix: potential crash in PSD visualization if road height is constant
4. made sure all possible selections of sections in road psd visualization work
5. ISO road class synthesizer made more accurate and respective analysis plot improved
6. made road PSD display is completely is visible for all screen resolutions

cosin/tools for tires

1. fix: kind of volume computation selection in case of higher speed mode
2. characteristics plot output window improved
3. fast and standalone TYDEX file checker introduced, not requiring an FTire/fit license

Documentation

1. chapters updated: cosin/io, FTire model, FTire parameterization, HiLAC, cosin/mbs
2. new contents: all FTire hysteresis elements, fast check for TYDEX file useability
