Hi Sina, Just to add yet another approach to what other people are suggesting... If you are open to using DEM to simulate it, Chrono DEM-Engine <https://github.com/projectchrono/DEM-Engine> offers the capability and a demo <https://github.com/projectchrono/DEM-Engine/blob/main/src/demo/DEMdemo_Plow.cpp> featuring a similar simulation. You can check out the rendering of the demo here <https://uwmadison.app.box.com/s/u4m9tee3k1vizf097zkq3rgv54orphyv/file/1277943467214>. You can refer to its README document for how to build and run the package.
The limitation would be that there's no ready-to-use interactive control of the blade, and it's expected that you control it using predefined motion or a programmable custom policy. Also, you need a Linux machine with GPUs to run it; however, in a few short days, the WSL and Windows version will be made available for everyone. Thank you!
