Hello Sina, we wrote a demo to demonstrate the "bulldozer" (gator + front blade) pushing a pile of soil (represented using CRM terrain). The demo is here: https://github.com/uwsbel/chrono-wisc/blob/project/leveling/src/demos/vehicle/terrain/demo_VEH_CRMTerrain_Gator.cpp. Notice this demo is at "chrono-wisc" instead of main chrono repo, so to run the same demo, I would suggest you to clone chrono-wisc repo: https://github.com/uwsbel/chrono-wisc.git and checkout branch "project/leveling". You will need the following modules: Vehicle, VSG and FSI. if you checkout this repo&branch, you could build the demo.
The paper is under anoynomous review now, which we probably can't share the paper for now and sorry about that.
