We use a unified formulation to simplify modeling of the various interface conditions---open pores, imperfect hydraulic contact, or sealed pores---that may exist between such media. Our numerical code is based on the clawpack framework, but in order to obtain correct results at a material interface we use a modified transverse Riemann solution scheme, and at such interfaces are forced to drop the second-order correction term typical of high-resolution finite volume methods. We verify our code against analytical solutions for reflection and transmission of waves at a material interface, and for scattering of an acoustic wave train around an isotropic poroelastic cylinder. For reflection and transmission at a flat interface, we achieve second-order convergence in the 1-norm and first-order in the max-norm; for the cylindrical scatterer, the highly distorted grid mapping degrades performance but we still achieve convergence at a reduced rate. We also simulate an acoustic pulse striking a simplified model of a human femur bone as an example of the capabilities of the code.<\/jats:p>","DOI":"10.1137\/130920824","type":"journal-article","created":{"date-parts":[[2014,5,22]],"date-time":"2014-05-22T11:54:02Z","timestamp":1400759642000},"page":"B396-B426","source":"Crossref","is-referenced-by-count":15,"title":["Finite Volume Modeling of Poroelastic-Fluid Wave Propagation with Mapped Grids"],"prefix":"10.1137","volume":"36","author":[{"given":"Grady I.","family":"Lemoine","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
