A suite of useful utilities to easily edit, analyze, debug and process FTire data files. This tool-box is included as standard with FTire/core or FTire/fit.

Key features

  • cosin/tools for tires is a GUI-based data file editor, which includes programs for static, modal, and steady-state analysis of FTire data files, as well as tool-kits for interactive simulation, linearization, reformatting of input files, and a lot more
  • cosin/tools for roads is a comprehensive road data file generator, browser, and converter for all kinds of road formats (RGR, track data files, openCRG, RDF, …)
  • cosin/ip is an advanced simulation results viewer
  • FTire/record is an offline replay simulation tool for FTire input signals
  • FTire/estimate allows data file estimation (‚morphing‘) based reference data and user-adjustable approximation formulas
  • Additional MATLAB-based post-processing tools
