Suitable for the latest hardware of personal computers, combining a discrete element code UDEC, MATLAB and EXCEL, a new method of comprehensive processing of amplitude of velocity/stress wave for every grid-point/zone-centroid for every zone was proposed. In the new method, some techniques were involved, including modifying the standard UDEC source code to increase the upper limits of time history and table amount, automating in UDEC input file the recording of the time history, by using the embedded language FISH, processing time history data in MATLAB to obtain amplitude data of velocity/stress wave for every grid-point or every zone-centroid. Some applications of the new method in rock dynamics were presented. Results show that the new method is of many advantages, and well suites processing the problems in rock dynamics.
