cosin software 2022-1 release notes

cosin

1. fix: potential endless loop when hitting Esc in graphics window with some solvers
2. improved slider display in animation window
3. introduced specification of more than one OLicense license files in GUI

cosin GUI

1. new red buttons in cosin launchpad for faster control of open or running cosin windows and applications

FTire/core

1. fix: potential crash when restarting multithreaded animation after aborting previous animation with ‘Esc’
2. fix: potentially inaccurate TYDEX transformation matrix output during statics computation
3. fix: improved numerics of output signal computation, to ensure total power loss cannot get smaller than sum of internal power losses.
   This fix might increase rolling resistance output in some cases, which is compensated by a more accurate specification of belt extension damp-ing, see bullet point 4
4. more accurate rolling resistance computation enabled by introduction of mod-ifiable segment-to-segment damping value (‘belt extension damping’)
5. new real-time capable hydroplaning model introduced, see FTire model doc-umentation for more
6. specification of kind of volume computation updated, introduced in GUI, and documented
7. correct gravity value (if not earth) in statics computation selected
8. improved volume computation and approximation
9. both structural and tread rubber stiffness and damping properties made sim-ultaneously modifiable during simulation using sliders, enabling more in-depth analyses of vibrational behavior

FTire/sim

1. fix: looped simulation in FTire/sim
2. more user-friendly selection of data files and simulation details in GUI

FTire/link

1. removed Matlab 32bit support (mex and slx targets)
2. set minimum version for Matlab mex and slx targets to 2016b

FTire/HILAC

1. added support for Adams RT in SimWB including rFpro/ABDynamics and Vi-Grade
2. extended cosin demo to manipulate velocity of the demo car via SimWB
3. added signal handler to get final statistics for FTire runs in SimWB
4. added SimWB ENV setting for FTire RT analytics
5. extended demo for using CarMaker+FTire on SimWB using IPG Movie

cosin/road

1. fix: writing of general soft soil data to file header when saving rgr data files
2. fix: specification of rendered vs. grid display of road in animation window
3. fix: error message if MSC’s xml road file is being loaded w/o MSC library avail-able or licensed
4. fix: potential crash with array-based road evaluation using VRcompute by VI-Grade
5. fix: ambiguity of parameter phi in rgr header resolved
6. added optional water-film niveau data to rgr header, see rgr documentation
7. new optional feature ds= or ds=sync in rgr header, to enforce exact syn-chronization between center-line path
8. coordinate and rgr x-position, useful for extremely long roads
9. new array-based rgr evaluation state save/retrieve to/from file/memory

cosin/tools for tires

1. optional reference plots added to fingerprint and characteristics plot
2. new drop-down menus for rim contour and intended tire use
3. easy-to-use import/export of FTire spline data as csv or mtl file for simplified processing in Matlab or Excel added to GUI
4. single-click spline data generation and export on basis of simplified geomet-rical specification added
5. data file comparison output made more user-friendly
6. improved fingerprint for two-wheeler tires: camber angle range adapted to kind of tire, camber thrust plot added
7. new interactive graphics-based cross-section editor implemented
8. cross section inner area output added to cross section plot
9. RTF factor computation comprises hydroplaning model if activated
10. cross section plot equipped with imperial units if selected by user
11. animation settings GUI made more user-friendly
12. new simple consistency check of modal damping values D1 vs. D2 added to GUI

cosin/tools for roads

1. stl file output completed by stl footer, needed by some CAD applications
2. visualization of huge rgr files with center line improved and accelerated
3. fast rgr file header read/write/change for huge rgr files introduced in GUI
4. made sure rgr roads with extra transformations are correctly displayed in animation window
5. improved crg -> rgr export: automatic dx/ds syncing added to exported header
