SPECFEM2D fluid-solid

[jiayujiayuj]

Description

I would like to ask you how to use Specfem 2d for forward simulation of ultrasonic sound field with fluid-solid coupling.(As a simple example, a 50mm x 50mm area, with solid iron in the middle 20 x 20mm area and water in the rest of the area, 10 excitation sources uniformly distributed on the upper surface of the water layer, with the receiver coinciding with the position of the excitation sources, and the excitation signal being Gaussian, how to solve the sound pressure wave field of the orthorectification using SPECFEM2D)
