generating unknown waveform in PML boundary #1183

Open snahn1 opened 1 year ago

snahn1 commented 1 year ago

Hi When inputting 1Hz Ricker wavelet, an unknown wave occurs at the PML boundary. Any solution for this? First of all, I am continuing to increase the PML thickness.

Thanks forward_image000230000
