Alex, There’s no reason why a particular suspension subsystem will influence the vehicle-terrain interaction. There must be something else that you are missing in your program. Does demo_VEH_SPHTerrain_WheeledVehicle work fine for you? A couple of days ago I modified that demo to include additional options for initializing the SPH terrain. The original code generated a pretty large terrain patch and so was taking quite a bit to run. The new version still has that option, but the default now is to create a smaller and coarser SPH terrain patch which runs quite a bit faster. Please make sure the demo works as expected (with the Polaris vehicle moving forward) and then see what it is that you are doing differently in your code.

But the parameters of suspensions, steering and chassis were different from those of HMMWV. I tested the vehicle to follow a straight line on SCM terrain, reference to demo_VEH_HMMWV, and it worked well. Then I tested it with same configuration on the SPH terrain, reference to demo_VEH_SPHTerrain_WheeledVehicle. There were no moving of chassis, and the wheel seemed to rotated in place. Is there any problem for the vehicle with simplified double wishbone running on SPH terrain?
