Note (General): This study proposes an element size selection method for 3D finite element elastic waves propagation analysis, under the condition time increment has been already selected. The method was named as Impact-Meshing method, according to the key idea to select an appropriate mesh by monitoring strain energy due to impact loading (static analysis), instead of the actual excitation (time series analysis). Because our method does not require time series analysis for mesh size selection, the total CPU time was reduced to be about 1/6 compared from that by the conventional method, for a case of 100 steps time series.
