С удивлением для себя я все чаще замечаю новую аббревиатуру для численных методов - DEM - Discrete Element Method.

LS-DYNA Discrete Element Method Analysis for Load Analysis of Mining Dump Truck Body | Predictive Engineering The discrete element method was used to simulate the load carrying capacity of a mining dump truck body. The LS-DYNA analysis investigated the stress response of the dump truck body during the shovel drop of a rock load. Figure 1 shows the basic setup of the model from initial loading of the shovel to final drop of the idealized rocks. The drop-test analysis work was used to bound a static stress analysis of the dump truck body. The finite element mesh was purposely made very coarse (see Figures www.predictiveengineering.com

Пока вот небольшой обзорчик консалтинга на эту тему. Позднее посмотрим, какие задачи можно решать данным методом. Может и у меня получится.
