Mesh adaptation for coastal ocean modelling in Thetis

Severn estuary

A tidal barrage is set in the Swansea Bay. Simulation of the full estuary is necessary to capture accurately the full tidal patterns.

Idealized estuary

Sinusoidal elevation is prescribed on the open boundary (half circle). Turbines can be placed in the channel.

Advected bubble in 2D and 3D

This test case was used to validate our mesh adaptation implementation in Firedrake.

Moving-mesh CFD simulations

Ejection of the door of an overpressured aircraft FSI simulation


Example of Fluid-Structure Interaction simulation: the door of an overpressured aircraft is ejected from the cabin.

Moving mesh

Engine piston


Example of moving mesh simulation with large variations of the volume of the bodies.

Rotating and translating aircraft


Simulation involving a rotating and translating rigid body with a complex geometry.
The geometry is the one of the IMR-2013 meshing maestro contest.

Swimming shark


Example of moving mesh involving deformable geometries and large displacements.

Unsteady mesh adaptation

Time-accurate adaption of a blast on a complex geometry (average mesh size: 2M vertices).

3D blast in a box

Classic test case of a blast in a rectangular box. Anistropic adapted mesh (left), density field (center) and density isosurfaces.
