<p>I was simulating the shear wave propagation based on the following paper:<br />
"https://asa.scitation.org/doi/pdf/10.1121/2.0000398"</p>
<p>So I can use the stress calculated from ARF using the pstdElstic. I managed to do that. But there is another way mentioned using volume force. According to the paper, the<br />
input velocity is automatically scaled to a force per mass (m/s2) by multiplying it with the factor 2c0/dxi where dxi is the spatial step in the chosen direction. To get a volume<br />
force Fi as input, we can therefore use an input velocity equal to (Fi*pho)/(2c*dx).</p>
<p>As K-wave only takes the stress or velocity as input. So Should I convert the ARF in to the velocity using the above relation and input it as velocity_x, velocity_y, and velocity_z in pstdElstic3D? Thanks for your time and looking forward to having your suggestions.
