- •
3D Moving Element Method (MEM) to model the track is proposed.
- •
The model considers an Eulerian coordinate system attached to the moving vehicle.
- •
The resulting formulation permits to reduce the computational cost compared to the FE models commonly used.
- •
The proposed 3D MEM track model is suitable to describe the high frequency dynamics.
