Finite Element Methods:

The geometrical flexibility of Finite Element Methods makes them ideally suited for the efficient computational solution of fluid-structure interaction problems. The figure below shows an example of the two Finite Element meshes used to solve the problem of Stokes flow in an elastic tube.

The fluid mesh consists of approximately 1200 brick shaped Taylor-Hood elements. The tube wall was discretised with 44 quadrilateral Hermite elements.

The fluid mesh is generated by an automatic mesh generator which adjusts the nodal positions in response to the wall deformation.
