| description | A comparison of second order and high order order (4th order, 8th order, 12th order)
finite difference staggered-grid method in 2D P-SV elastic wave propagation has
been made. A graph comparison of dispersion and accuracy of inter order are made
to show stability condition of each order. CUDA C programming language is used
to finite difference staggered-grid method to see the process time difference
between second order and high order in GPU NVIDIA GeForce GTX 590 (1,5 GB
memory) quantitatively. This program has been verified by comparing travel time
of direct wave, reflection, refraction, and conversion between synthetic seismogram
and analytical line from two layer medium using Snell�s law. The agreement is
excellent. Program are applied to one layer medium and complex medium
(Marmousi-2). The time process result of one shot with 5,28s duration at Marmousi-
2 model slice with size 4800�2400 grid are 1168,72 s (2nd order), 1736,40 s (4th
order), 2816,80 s (8th order), dan 3778,67 s (12th order). The difference of
seismogram result between second order and high order on two layer model
indicated that numerical dispersion has occurred on the waveform. Furthermore, a
contrast difference result also seen in Marmousi-2 model seismic data record that
seismic data record from second order still has a lot of numerical dispersion effect. |
