Hi Heming, This problem is something that we’ve never done in Chrono. In my mind, it’s a hard problem. It can be done, but it’d take some thinking and tinkering with the code. Your best bet is to use the DEM code (https://github.com/projectchrono/DEM-Engine) and rely on the customizable inter-particle force model that is available therein. In other words, you can control how two particles in contact interact with each other, that is, what the interaction force for mutually interacting particle looks like. That callback function provides an avenue to introduce the particle moisture in the model. You would run, for instance, a tracked vehicle using Chrono::Vehicle and co-simulate with the DEM code, which runs on the GPU. Which means that if you pursue this solution, you should have one GPU, and preferably two, available on your workstation. Good luck with your project.
