The discrete element method (DEM) is used to establish the particle model, and the finite element method (FEM) and multibody dynamics (FEM-MBD) are applied to establish the structural model. The time step of the coupling algorithm between particles and a structure is discussed. The calculation...
The lander is regarded as a multibody system composed of a cabin, legs and footpads, and its motion characteristics are solved by multibody dynamics (MBD). A DEM-FEM-MBD coupling algorithm is developed to simulate the landing process of the lander considering landing mode and buffer mechanism, ...
I was new to DEM simulation and had to complete a complex project in a short period of time. ThreeParticle was very easy to pick up and the outstanding expert support from BECKER 3D ensured that we were able to get the most out of our simulations. Jack Chartres | QING Groep There is ...

Considering the complexity of DEM-FEM-MBD coupling algorithm, the modeling process is divided into three parts: set up the discrete element model of lunar soil, building the finite element model of lander, and determining the connection mode of multibody structure of lander. The three parts will...
