cosin software 2022-3 release notes

cosin

1. fix: potential DOE slider crash
2. maximum formula string length set to 1024 for efficiency reasons
3. improvements in cosin/ip:
   a. new command noxsignal, showing sample index on x-axis instead of independent variable
   b. fixed sort commands
   c. re-arranged PSD-related entries in GUI

FTire/core

1. new naming ‚carcass/belt neutral axis‘ instead of potentially misleading ‚carcass line‘ in message and file output
2. made sure FTire/statics completes under all circumstances even if diagnosis animation window is shown
3. allowing formula expressions instead of constants for initial operating conditions in tir-files

FTire/fit

1. fix: potential crash in cleat test identification
2. fix: minor issue with caption generation in FTire/fit report
3. ‚optimize numerical settings‘ computation accelerated
4. new analysis button in GUI: parameter score sensitivity analysis
5. added all missing terms for optional second inflation pressure selection
6. new ‚combined identification‘ mode added to GUI for improved determination of parameters that simultaneously depend on different kinds of measurements
7. score computation in FTire/fit improved and consolidated
8. project loading time shortened

FTire/link

1. fix: made all auxiliary cosin windows called from Simulink blocks work
2. made sure more than one single-threaded or multi-threaded FTire/link block can be run in one Simulink model
3. made external drum speed control in Simulink work with standard road file cosin_drum.rdf

FTire/HILAC

1. added support for Adams Real-Time on SimWB using VI Roads and ViDriveSIm environment

cosin/road

1. fix: array-based rgr evaluation observes road motion data now
2. maximum length of cosin/io- and TeimOrbit-formatted stochastic roads in animation increased to 2 km; as before, for pure simulation w/o road animation model, roads are arbitrarily long
3. road animation model accelerated for rgr with center-line roads

cosin/tools

1. make record file replay be aware of non-trivial road motion data
2. enabled animation for tire>1 in record file replay
3. enabled message window display in record file replay

cosin/tools for tires

1. rim compliance plots added to fingerprint
2. available characteristics plots completed by vertical deflection on cleat
3. meaning of additional design parameters in sim-scripts for characteristics plots added in terms of GUI tooltips
4. n_tire_states data item added to interface numerics GUI
5. optional time tables for operating conditions preserved when editing and saving a tir-file

cosin/tools for roads

1. made array-based rgr roads work in 2d and 3d visualization
2. made sure basic road info is shown in GUI even for huge rgr files
3. made sure rgr files can be plotted in automatic mode even for huge files
4. allow more complex arithmetic formulae in road builder; improved error message if arithmetic expressions are too complex
5. center-line extraction from rgr takes into account now non-trivial friction coefficients
6. road info output in visualization window completed
7. improved user info when loading huge crg files in cosin/tools

CTI (cosin tire interface)

1. occasional strong initial transients caused by external solvers frequently going backward in time during first steps considerably reduced
2. solver-individual settings in co-simulation pane of cosin launchpad introduced
3. minimum solver step size in case of step-size control made configurable
