I can't adjust the fragmentation of solid models

I want to follow the progress of a vehicle I designed on Solidworks over an obstacle, but when I add the contact force, my vehicle starts to fly. I am very new to Matlab application, can you help me with this?

A probable cause is that your vehicle is starting the simulation already penetrating the ground, this can be fixed by either displacing the ground down using a rigid transform or by setting state targets in the sixDof joint to initialize the vehicle above the ground

First of all, thank you for your answer. Please excuse me if my English is bad. I have set it up so that there is enough distance between my vehicle and the ground. When I design a solid object via Simulink and apply force, there is no problem. Do I need to change the force values ​​and if so, how should I calculate these values?

I think it would be best if you can upload a video that shows the behavior, and/or attach the model
