Fig. 3From: A hybrid interface preconditioner for monolithic fluid–structure interaction solversGeometry of pressure wave through an elastic tube—a solid tube (outer radius \(r_o={0.6}\,{\hbox {cm}}\), inner radius \(r_i={0.5}\,{\hbox {cm}}\), length \(\ell ={5.0}\,{\hbox {cm}}\)) is clamped at both ends and is filled with an incompressible Newtonian fluid that is initially at restBack to article page
