cosin graphical user interface (GUI)

1. GUI window placement in Windows optimized
2. made sure kind of licensing is remembered in launchpad GUI from call to call

FTire/core

1. fix: wrong volume output signal scaling
2. fix: improved selection of optional additional rim CAD model rotation in GUI
3. accuracy of volume vs. deflection characteristic approximation improved
4. made sure changes in properties for second inflation pressure always trigger fresh pre-processing
5. made sure only relevant contact elements near contact patch area saved as contact candidates
6. new parameter: low-pass filter time constant for TPMS acceleration signals
7. new warning output if pressure-based interpolation creates zero stiffness or damping value
8. optional extra rotation of rim CAD model introduced
9. rim CAD-File calibration extended to truck rims having parts outside rim flanges
10. tire construction, kind, and type specification homogenized
11. recognition of ETRTO string fixed, if speed symbol is W and no rim size is given

FTire/sim

1. fix: parallel simulation in FTire/sim in windows fixed
2. made sure animation selection in FTire/sim is preserved if sim-file editor is launched
3. plot signal selection fully integrated in FTire/sim GUI

FTire/fit

1. fix: check in after ‚what if‘ inquiry might have caused error
2. fix: creation of FTire/fit-compatible colored footprints
3. fix: FTire/fit project creator in case no measurement with useful tire size specification is found
4. fix: potentially incomplete plots in FTire/fit
5. fix: FTire/fit project creator wizard fixed
6. fix: FTire/fit: repeated check in/out fixed; image preparation for colored footprints introduced
7. fix: generation of FTire/fit-compatible footprint images
8. made sure all tabs in FTire/fit are immediately shown after any demo project renewal

cosin/tools

1. fix: curve follower selection in cosin/ip fixed
2. fix: file selection in cosin/ip GUI
3. fix: potentially wrong missing license errors in cosin/ip
4. made cosin/ip more reactive wrt. signal activation in image
5. made signal definitions in cosin/ip with two alternatives work
6. made sure correct file is inactivated with right click in cosin/ip’s file list
7. made sure license check in cosin/ip works as intended
8. make blocking ASCII editor in cosin/tools work properly
9. new cosin/ip command ‚uselast‘
10. new Butterworth differentiation filter

cosin/tools for roads

1. fix: potentially missing friction factor value in old ‚METH 2D‘-rdf-evaluation
2. fix: list of dependent road files
3. ensured that the get-dependent-road-files algorithm does not add the road itself to the dependent list
4. improved PSD plot in road tools
5. new placeholder data file for urm (user-defined road models) road models
6. road generation based on PSD improved

cosin/tools for tires

1. fix: behavior of FTire/estimate if two inflation pressure values are set but only one is specified in reference data file
2. fix: save logic if tire data file has newer version than actually used cosin/tools
3. ETRTO string consistency check added to cosin/tools for tires
4. static image creation added as new tire action choice to database evaluator
5. new analysis button to display all kinds of FTire-related label sets

cosin/tools for Matlab

1. fix: message window behavior in Matlab
