Flexural wave scattering

Authors: Peter Nekrasov, Zhaosen Su, Travis Askham, Jeremy G. Hoskins

Here, chunkIE is applied to a new boundary integral formulation of the free plate boundary condition for flexural wave propragation in thin plates.

Linearized water wave problems

Authors: Travis Askham, Tristan Goodwill, Jeremy G. Hoskins, Peter Nekrasov, Manas Rachh

For the image above, chunkIE (and fmm3dbie) were used to compute the scattering of linearized water waves off of a realistic ice sheet rift geometry.

Corrugated Helmholtz waveguides

Authors: Fruzsina Agocs, Tristan Goodwill, Jeremy G. Hoskins

For the image above, chunkIE was used to compute the scattering off of a junction of corrugated waveguides with embedded Neumann obstacles.

Large waveguide circuits

Authors: Tristan Goodwill, Shidong Jiang, Manas Rachh, Kosuke Sugita

For the image above, chunkIE was used to compute modal impedance to impeadance maps for individual junctions. The total system was then solved using a domain-decomposition method.

Acoustic boundary layers

Authors: Jacob Linden, Travis Askham, Jeremy G. Hoskins

In this example, chunkIE was used used to solve the Helmholtz equation with visco-thermal boundary conditions. The geometry is inspired by the cross section of a speaker phase plug.
