Introduction to AcuSolve Computational Fluid Dynamics - EDEM coupling

PM-FlexTire deformable tire model for use with EDEM soil models and ADAMS or Motion Solve. PM-FlexTire is an finite element-based tire model that is integrated with the Altair® EDEM™ soft-soil simulation platform and significantly expands what is possible in virtual development of soft-soil mobility. The model provides realistic deformation and high fidelity forces and moments through co-simulation between EDEM and multi-body dynamics (MBD) codes. Included time-varying air pressure model and detailed tread pattern interaction with particles are features unique to PM-FlexTire. Users can create models from tire CAD using various meshing solutions including Altair® HyperMesh® and Gmsh integrations, or use meshes generated from other third party meshing tools. Comprehensive integration with discrete element method (DEM) simulation provides a high level of utility relative to alternatives to support increased scope of virtual development. Simulation complexity and licensing cost of PM-FlexTire and the corresponding integrations are "best fit" for virtual mobility development in soft-soil DEM simulation environments.
