Utilities for tire simulation control

The Adams Tire toolkit contains a few consub functions that will allow you have control for quasi-static equilibrium calculation for a single tire, FTire output, and redistribution of tire mass and inertia.
 
ID
Description
con901
Redistributes tire wheel mass and inertia: assuming that the wheel part contains the total wheel mass and inertia, it will subtract the tire belt mass and inertia.
par(1) = 901
par(2) = Id of the array with the tire input_array
par(3) = wheel part id
par(4) = belt part id (if not available 0)
par(5) = method:
0 for tire testrig, 1 for full vehicle simulations
par(6) = id of tire gforce
Note: This consub is supported only when using the CTI interface ('USERCTI')
con903
Routine to perform a quasi-statics for a single wheel:
par(1) = id of the tire gforce
par(2) = id of the JPRIM
par(3) = id of the wheel part
par(4) = id of the belt part (if not available 0)
par(5) = id of array with part id's to be with the forward velocity
par(6) = desired wheel's forward velocity
con904
Routine to generate a step long slip input for the tdft adv. long. relaxation length
par(1) = id of tire gforce
par(2) = id of the motion of the wheel rotation
par(3) = start time of the step
par(4) = amplitude of the step in % wheel slop
cfinit
Sets the output generated by FTire:
par(1) = id of the string with the file prefix (simulation file name)
par(2) = switch for .rgu output (in case of soft soil modeling)
par(3) = switch for .ogl output (for integrated Ftire animation in the Adams Postprocessor)
par(4) = switch for FTire live animation during the simulation
a switch has the option off/on: 0/1
