cosin software 2011-2 release notes
  1. New FTire computation mode: 'compute forces on car body', to calculate tire, rim and suspension dynamics by the FTire solver using MBS suspension models based on cosin/mbs
  2. New CTI/server and CTI client API (CTICLI). Enables applications running CTI commands on a remote computing server over a network connection. This allows using FTire on systems where a local CTI library is not applicable (embedded systems, HIL platforms), or setting up a common FTire computing server. CTICLI is designed as an extension to CTI and redirects CTI commands to a remote computer with only minor modifications to existing CTI interface code.

  11. Ghostscript (needed for report generation) included with Windows installer now
  12. Conditional expressions in cosin/io data files introduced to improve flexibility of FTire/sim and cosin/mbs scripting
