Did you find that?</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/similarity-between-elastic-and-fluid-models#post-8602 Mon, 05 Sep 2022 09:35:22 +0000 s148275 8602@http://www.k-wave.org/forum/ <p>Hello,</p> <p>I have been using both the k-space fluid model with power-law attenuation (kspaceFirstOrder) and the viscoelastic model (pstdElastic). I was wondering if the viscoelastic model will reduce to the fluid model with power-law attenuation if you set the shear velocity and attenuation to zero for the viscoelastic model and the power-law coefficient to y=2 for the fluid model?</p> <p>Thanks in advance!</p> <p>Best regards,<br /> Frank </p>
