That’s correct. For something like demo_FSI_Flexible_Toroidal_tire, it’s easy to build the meshes for all flexible tires within the same ChMesh object. But that’s not the case if you want top use a vehicle model with its own flexible tire models (as those encapsulate their own ChMesh objects). --Radu

How can I model multiple flexible tires with a single mesh? Can I implement it with the implementation of demo_FSI_Flexible_Toroidal_Tire? Best regards, Alex 在2024年3月13日星期三 UTC+8 16:04:57<Radu Serban> 写道： Alex, you are correct. Currently Chrono::FSI is limited to working with a single FEA mesh. To model multiple flexible tires, you would need to put all nodes and elements into a single mesh. Better support for FEA in Chrono::FSI, including allowing multiple meshes, is something that is on the todo list and will be worked on soon.

Hi everyone, I tried to model vehicle with four flexible wheels in a CRMTerrain. I referenced demo_VEH_CRMTerrain_WheeledVehicle and demo_FSI_Flexible_Toroidal_Tire. However, the simulation was stopped at the step of terrain.Initialize(). I tried to modelled two flexble wheel in demo_FSI_Flexible_Toroidal_Tire, and the simulation also stopped at the stage of terrain.Initialize(). So, is only one mesh allowed in the CRM-FEM cosimulation? Best regards -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
