Working in ADAMS/CAR 2017.2 version. I am running a full vehicle simulation on a rough road (Kind of Belgian Pave road) at a constant speed.
For the Full vehicle model with Torsion and Control arm suspension bushes are set as "Standard bushes (*.bus)) runs without error with GSTIFF/I3 solver.
But, when I replace the standard bushes with "General Bush definitions", the simulation Locks up at the initial stages of dynamic simulation.
The simulation runs without error with GSTIFF/ SI2 solver, but computation time is almost 5 times that of GSTIFF/I3 at 0.01 error.
Setting error at 0.1 with GSTIFF/SI2 improves the computation time to 1.2 times of the GSTIFF/I3 solver.
The question is -
(I) Am I missing any basic understanding that if we use General bushes GSTIFF/ I3 solver is not to be used?
(II) Ultimately, I am calculating Force at the bush attachment points. Compared attachment loads for 0.01 error & 0.1 error results. . Spikes were observed with 0.01 error which are missing with 0.1 error. In other locations - minor variation in the magnitude was observed. Does anyone else have such observations? Is it OK to go with GSTIFF/SI2 error 0.1 when using General bushes?
