Can Project Chrono realize the coupling of tracked vehicle dynamics and discrete element?

[旺旺仔]

Dear perfessors,

I want study the interaction between the tracked vehicle and cohesive soil pavement.

Can Project Chrono realize the coupling of tracked vehicle dynamics and discrete element?

Thank you!

Hi,

If a coupled simulation between a DEM system and a Chrono-managed multibody system is what you wanted, then definitely yes. For DEM, it is supported through a separate Chrono toolkit, DEM-Engine. You can check out the README document to see if it fits your needs. If it does then you can proceed to install it as a library so it works together with Chrono core.

Of course, there are other terrain representation types other than discrete elements, too. But I am not familiar with those.

Thank you,

Ruochun

In addition to what Ruochun suggested, look also at the co-simulation framework in Chrono::Vehicle which allows you to simulate vehicles (wheeled and tracked) on any of the deformable terrain models available in Chrono, as well as coupling Chrono::Vehicle models with third-party terramechanics packages.  Currently, for granular dynamics the co-simulation framework only supports the Chrono::Multicore module (CPU multicore parallelization) and the Chrono::GPU module (single-GPU implementation).  When I find some time, I will also include support for the stand-alone DEM-Engine package that Ruochun mentioned.
