Abstract

Mesh size influence on dynamic modeling im 1-D and 2-D models is investigated by using discrete element code UDEC. It is shown that the modelling with smaller mesh ratio obtains higher accuracy, which agrees well with the common acceptance. Furthermore, it is found that the error, induced by the mesh size, increases with increasing distance from the wave source and also with increasing wave frequency. Therefore, it is suggested that the mesh distortion may resulted by a combination effect of mesh size, wave frequency and distance from the wave source. Comparing the results between 1-D and 2-D models indicates that the 2-D modelling produces higher error than 1-D model, which is explained as due to the error superposition in x and y directions in the 2-D model.
