Step-by-step instructions on how to reproduce issue:

You can attach up to 3 files. Please attach the following:

  • a consolidated parsfile (CarSim 8+, TruckSim 8+) or an expanded parsfile for the run in question
  • any Simulink models being used
  • a screenshot of any error messages received.

NOTE: To create the Consolidated Parsfile or  Expanded Parsfile,
Go to the run of interest while viewing the Run Control screen.
Use the File menu item Export Consolidated Parsfile (CarSim 8+, TruckSim 8+) or Expanded Parsfile (BikeSim, and earlier CarSim and TruckSim)... to create the file.

The reason we ask for an Expanded Parsfile and any Simulink models is so that we can duplicate your problem. Once your issue is solved, we delete all data.

Size limit: 20MB combined total of all files. If you have larger files to submit, please note it in your description. We can arrange an alternate method of transfer.
