Running a User Tire Model in SMP solver mode
By default user tire models are considered to be not thread safe. In order to allow the solver to run a user tire model in multi-threaded (SMP) mode, specify the thread safety of the tire model by making following call during jobflg = init:
CALL ADAMS_USERTIRE_DECLARE_THREADSAFE()
