Concurrent simulation of multibody systems coupled with stress–strain and heat transfer solvers

In the present work multibody 3-axis truck vehicle model coupled with submodels of suspension bodies is considered. Coupling the main model with submodels allows to perform simulation of multibody dynamics and non-stationary heat conduction and stress distribution processes in bodies simultaneously. High efficiency of parallel simulation on computer cluster is achieved using developed software based on MPI library.

► We concurrently simulated 3-axis truck coupled with suspension parts submodels.
► Weak coupling of solvers provides small amount of data transferred during sync.
► Parallel implementation using MPI library was tested on 6-nodes cluster with MPICH2.
► Efficiency of parallel simulation decreases in case of small meshes.
► Efficiency of parallel simulation remains high in case of large meshes.
