cosin software 2023-3 release notes

General cosin software aspects

1. fix: potential use of wrong emulated version after change in launch-pad
2. copy/save function added, by right click in all files listed in application file statistics
3. improved tooltips usage selection in GUI menu bar

FTire/core

1. fix: potential numerical issue in computation of volume gradient value during pre-processing
2. fix: potential slight dependency of output torque on numerics and direction of travel of y component in case of RT force extrapolation
3. new output signal: ‚total CPU time w/o communication overhead [s]‘
4. compressed storage of pre-processed data in tir-files introduced, considerably reducing tir-file size

FTire/fit

1. fix: ‚what if‘ output potentially empty if verbose message window is switched off
2. fix: check-in of vertical stiffness measurements: misleading warning message „inflation pressure does not match supported test conditions“ removed
3. fix: potentially inconsistent units used for VMAX in FTire/fit
4. fix: in cleat test simulations: tire rotation speed might start with wrong value
5. fix: validation of cleat tests might not work if character ‚ (single quote) is included in project folder name
6. FTire/fit prepared for non-pneumatic tires (NPT)
7. new FTire/fit toolbox for Matlab implemented, to access measurements checked in by FTire/fit for identification using Matlab optimization functionality, see documentation
8. improved resolution in FTire/fit image output
9. modified GUI script to create new demo project without any user input
10. refreshed FTire/fit demo data by new measurements

cosin/road

1. fix: physical unit scaling in center-line banking evaluation
2. sped up full 3D triangulation evaluation in case of a single moving body
3. full 3D road animation model improved
4. added optional road transformations after loading pure rgr roads, at run time

cosin/tools

1. automatic and complete support of all 4 unit systems (independent on unit systems used in plot files) implemented in cosin/ip
2. error and warning messages output in cosin/ip made more user-friendly
3. function plotting added to helpers menu, based on general arithmetic expression for function
4. made curve follower function in cosin/ip smoother
5. new plot file reformatter added, exporting any supported cosin/ip file format to one of mtb,mtl,tdx formats

cosin/tools for roads

1. fix: road tools ’new rgr road‘: buttons ok, cancel, preview, apply might have been invisible
2. quotes added to ROAD_VERTICAL entry in rdf files, to make files readable by all 3rd-party environments

cosin/tools for tires

1. fix: cosin/tools started from Adams/Car GUI on Linux could not open a tir file saved in cosin private data folder
2. fix: viewing of tir file numeric properties might have changed the run time mode
3. new tir files with variations of some parameters added to set of example files in installation package

CTI (cosin tire interface)

1. fix: potential crash if cti/sim is called in RT speed mode for other than rgr road type
2. added non-blocking mode for ctiReadStatesMemoryList API function
3. added respective message to ctiWriteStatesMemoryList API function output in case force extrapolation is active
4. new API function ctiGetRoadModelType
5. ctiMoveRoad API function supports now all kinds of roads

CRI (cosin road interface)

1. added new CRI API function criGetRoadModelType

Documentation

1. added tire variations documentation and fingerprint instructions
2. FTire/fit Matlab Toolbox documentation added to FTire/fit chapter
