Abstract

Purpose

The purpose of this study is the reduction of computational time demand of discrete element based modeling.

Design/methodology/approach

The methodology is the systematic changing of particle size and micromechanical parameters to reduce computational time requirements.

Findings

In some cases, the computational demand of discrete simulations can be reduced to about 95 per cent.

Originality/value

Based on the results and demonstrated methodology, the enormous computational time demand of discrete element-based modeling can be reduced significantly.
