Abstract:

Based on the discrete element method and computational fluid dynamics method, the software for the analysis of dense fluidsolid interaction and the flow was developed, and the integration with threedimensional computer aided design software was achieved, then a new computer aided engineering softwareAgriDEM with design and analysis and evaluation of the performance was developed. The correctness and validity of the software were verified by some examples.

Key words: discrete element method (DEM), computational fluid dynamics (CFD), computer aided design (CAD), computer aided engineering (CAE), optimal design
