cosin software 2020-3 release notes

cosin GUI

1. made sure GUI shows respective buttons if ftire_adams license key is available

FTire

1. fix: colors in contact patch display at tire
2. fix: if tir-file contained spline data for temperature dependency, pre-processed data properly reflect this now
3. fix: output sequence of nodes in cfo-files
4. fix: curvature computation in rim-fixed TPMS sensor
5. short non-editable tir-files introduced; basic data given only inside coded PA array
6. error message for unsupported compatibility date introduced
7. ’show footprint from above‘ added to animation window selection menu
8. enhanced slider display in animation window
9. made sure animation time control is taken from animation settings file if this has priority over tir-file
10. visualization of LTI matrix structures and sparsity patterns improved and activated
11. new selectable positions of TPMS sensor: left/right rim flange
12. ‚earthmover/OTR‘ added to tire kinds set

FTire/sim

1. quarter car model stabilized to run even with numerical time delay
2. avoid loading same road data files twice in FTire/sim

FTire/link

1. fix: potential Matlab crash when tir-file is non-existent

FTire/HiLAC

1. added support for SimWB 2019.3-3 and 2020.1-1
2. redesign of SimWB coupling: FTire/core SimWB models use now multi RTDB mechanism to couple FTire/core with any other model easily via model 2 model communication within SimWB (requires minimum SimWB version 2018.2)

cosin/road

1. made sure center-line files with multiple linked rgr files load all rgr files when needed
2. automatic recognition if display grid is too large for center-line road to give unambiguous projection
3. improved combination of rgr files implemented, including proper combination of attributes including friction factor and soft-soil definition
4. making sure all kinds of rotation of rgr files does not affect rgr combination; combined rgr files are centered
5. make sure all optional road transformations are observed in all automatic rgr animation models
6. made sure road evaluation count works in all speed modes

cosin/mbs

1. improved GUI and animation window layout

cosin/tools

1. write correct units for all supported unit systems in cosin/tools GUI
2. new if/elseif/else/endif construct available in cosin/ip scripts
3. definition of alternative signal names introduced in cosin/ip
4. new button in launchpad for simplified access to FTire database

cosin/tools for tires

1. FTire demo model made up: side-wall texture and grooves added to animation
2. confusing progress bars during fingerprint generation no longer shown
3. tire surface gray scale made selectable in animation settings GUI
4. made sure soil.tir and tread_pattern.tir provide finger-print w/o warning
5. FETire/static GUI redesigned
6. formula treatment in GUI fixed
7. show all errors and warnings in fingerprint log file in case fingerprint computation failed
8. tire construction selection redesigned in GUI; all construction types can now be selected with a drop-down menu
9. all example tir-files updated and reformatted
10. all FTire-related multithreading functions simplified and unified
11. parallelized FTire/statics and FTire/steady-state evaluation implemented, generating tremendous speed-up of properties calculation

cosin/tools for roads

1. fix: configurable 3D plot of closed center-lines
2. GUI redesigned
3. attribute indices in road builder now definable via image, similar to height value
4. improvements in RGR road builder:
   • new thumbnail images in GUI
   • random multiple placement in ‚add‘ mode (works for all kinds of height and attribute definition)
   • when rgr data are defined with images: determination of up to 5 dominant colors and optional assignment of height/attribute values to these colors
5. made sure road rotation etc. in road builder is effective if imported road provides data
6. in road builder, indexed data are kept now when center-line is added in all 3 modes: generate/reformat/resample

CTI (cosin tire interface)

1. added ‘private data folder’ as item = 6 to ctiGetInstallationInfo

CRI (cosin road interface)

1. added ‘private data folder’ as item = 6 to criGetInstallationInfo

Licensing

1. fix: changes in license setting are not always effective in simultaneously opened/operated other cosin GUIs
2. made sure tir-file speed mode can be changed with classroom license

Documentation

1. fix: incorrect bso/rfo output descriptions
2. new/updated FTire/HiLAC documentation
3. updated FTire/sim documentation
4. fixed parameter lists of cticliLoadRimData, cticliLoadRoadData, cticliLoadSuspensionData, cticliLoadTireData and cticliGetServerStats
