Model Fidelity Reduction - Tires

Setup → Model Simplification → Tires

Converts any tire property file to a PAC2002 tire property file with reduced functionality to reduce simulation times.

For the option:	Do the following:
Select Tire
Tire Property File	Select the tire property file that want to convert for making the tire – road contact modeling faster. The menu lists all the used tire property files in your assembly.
Tire Model	Shows the tire model (format) name of the selected tire property file
Model Type	Select what type of dynamic tire response is desired. The options listed below: ■No transient ■Transient ■Belt Dynamics The selected tire model needs to cover the selected type. For example, a standard PAC89 model will not show the Belt Dynamics option.
Contact	Select type of contact model in between the tire and the road: ■One Point (default) ■3D Enveloping Contact, for covering short wavelength obstacle impacts (time consuming).
Tire Data and Fitting
Tire Data Fitting Tool	To launch the Tire Data Fitting Tool for converting the tire property file to a PAC2002 tire property file with the setting from page 1.
PAC2002 Options
Number of Cams	Specify the number of cams used by 3D Enveloping in longitudinal and lateral direction (separated by a comma). A Default setting and a High Performance setting (less cams) can be defined.
Contact Threads	Specify the number of threads that can be used by 3D Enveloping contact. A Default setting and a High Performance setting can be defined.
Road Spacing	Specify the road grid size to be taken by the 3D Enveloping contact. A Default setting and a High Performance setting can be defined.
Local Tire Solver	Specify if the tire states should be calculated by the tire model itself (local solver) or by the Adams Solver (via GSE). A Default setting and a High Performance setting can be defined.
Save	Saves the converted tire property file with the default name: <original tire property file name>_PAC2002.tir in the working directory of Adams Car.
Save As	It will save the converted tire property file with your specified name and path.
Replace Tires in Assembly	If checked, during ‘Save’ or ‘Save As’ the original tire property file in your current Assembly will be replaced with the converted tire property file.
Use HP mode	If checked, and if the original tire property file in your current Assembly will be replaced with the converted tire property file, the High Performance use mode will be switched on.
