When defining the seismic amplitude, a smoothing parameter of 0.05 is suggested for amplitude definitions containing large time intervals to avoid severe deviation from the specified definition.
Infinite elements extend the finite element method to simulate far-field regions, effectively modeling semi-infinite domains without requiring prohibitively large model extents. For soil-structure interaction problems, infinite elements are applied to soil far from foundations to capture boundary effects and prevent artificial wave reflections. abaqus earthquake analysis
