cosin software 2020-2 release notes

FTire

  1. fix: made sure sidewall geometry is correctly pre-processed (wrt sorting of nodes) even for extreme tire sizes
  2. polynomial smoothing of cross section geometry data now applies also to carcass contour data
  3. recognition of mirroring necessity of contour data made more robust
  4. made sure convergence fail in FTire initialization throws a correct warning
  5. more accurate high precision contact calculation
  6. new misuse model: belt puncturing and consecutive air mass/pressure loss through extremely sharp obstacles
  7. new misuse treatments ‚tire puncture‘ and ‚tire bead slipping off rim seat‘ activated in all real-time levels
  8. optional simplified bottoming model (using center emergency ring) for real-time applications

FTire/fit

  1. fix: FE results import in case of global coordinate system
  2. fix: made sure score values are saved correctly even if not all FE result cases are activated
  3. 1D parameter variation in Global Scanning optimizer fixed
  4. rectangular portion of belt to be used in FE cases identification made configurable in FTire/fit settings
  5. new selection: in FE result cases, compare only vertical component of displacement vs. compare full spatial displacement of nodes
  6. generalization of identifiable parameter specification and parameter dependencies in FE result case identification
  7. ‚what if‘ function improved: shows FTire parameters that will be modified with test result import, as well as inflation pressure case
  8. detailed sensitivity study (button ’sens.‘) added to GUI, tab ‘FE result cases’
  9. improved run-time error handling
  10. x/y/z displacements made individually selectable in tab ‘FE result cases’ validation/identification
  11. avoiding unnecessary pop-up of statics animation window in FTire/fit steady-state simulations
  12. footprint adjustment wrt grooves added to footprint validation/identification
  13. kind of footprint evaluation (with/without pressure distribution) now saved as part of project settings

FTire/sim

  1. type of displayed roads in FTire/sim GUI made selectable by drop-down menu

cosin/road

  1. fix: made sure no wrong ‘emulated cosin version’ is set if cri functions are called w/o loading a tire data file
  2. fix: scaling corrected in road profile generator for ISO road classes (original version might have created too small amplitudes). Fix can be deactivated for downward compatibility via ‘emulated cosin version’
  3. consolidation: obsolete cosin evaluation of crg roads removed
  4. new road type: dynamic height array import from viCarRealTime

cosin/tools

  1. single-step mode in ogl file player improved
  2. ogl file player equipped with slider control (similar to most movie players)
  3. small drop-down menus in all GUIs made better readable

cosin/tools for tires

  1. reorganization of parameter groups in edit menu; new group button ‘misuse / damage’
  2. all tire data example files equipped with meaningful rim-to-road contact stiffness data

cosin/tools for roads

  1. fixes in image-based rgr generation
  2. fixes in ‘add data’ functionality for rgr roads
  3. optional low/high pass filter added for all kinds of data to be added to an existing rgr
  4. rgr export for arbitrary road formats from within 3rd-party environments added
  5. made sure road tool preferences are reset to default if new road is loaded in GUI
  6. made sure new rgr grid size & resolution is not overwritten if new height data source is specified in rgr builder
  7. homogenization and simplification of road attribute specification in all kinds of road visualization
  8. more new features for rgr road visualization

cosin/tools for MatlabTM

  1. new M-script to visualize fer modal files

CTI (cosin tire interface)

  1. fix: reading animation settings from cti-file might have returned wrong file names for animation-related files
  2. fix: ogl file issues, as reported by MSC for Adams Post-Processor
  3. execution time of certain auxiliary cti functions reduced
  4. new API function ctiGetRoadProperties() to query current road properties
  5. assure record-file mode is set correctly for all ways to set multi-threaded call flag

CRI (cosin road interface)

  1. new API function criGetRoadProperties() to query current road properties
