Description of the animation:
The start of mixing optimization with the
"Mapping Method" is an accurate computation of the velocity field. The
lack of information in the spreading of massless particles demonstrates
the inadequacy of the present approach in the
literature.

Description of the animation:
This movie shows the deformation of two
blobs
in a
rectangular cavity. The mixing
protocol
consists
of a periodic motion of the top
and
bottom wall.
The left blob is positioned around
an
elliptic
periodic point, the right blob around
a
hyperbolic
periodic point.

Description of the animation:
Blanking is a forming process which is used to cut product out of sheet metal. Fine-blanking uses an additional counterpunch to induce compressive hydrostatic stresses and thus delay the development of damage and fracture, resulting in a better product surface. The movie shows the evolution of the equivalent stress and the stress triaxiality in the region where the cut is made.

Description of the animation:
A knife is used to produce a score (indentation) in thin sheet metal. The simulation uses a coupled plasticity-damage model to predict damage and fracture of the sheet and remeshing to trace the resulting geometry changes. On the left the evolution of the mesh (including crack) is shown, whereas the right part shows the evolution of damage.

Description of the animation:
Mixed-mode loading of a pre-cracked aluminium specimen results in crack growth at an angle. The growth direction and speed are predicted by a ductile damage model and traced computationally using remeshing. This movie shows the evolving finite element discretisation, together with the predicted load-displacement response.

Description of the animation:
The 3D FE-model (left) simulates the free swelling experiment (right) of the intervertebral disc. Usually (body), the disc is gripped between two vertebrae and surrounded with a physiological salt solution. This restrains the disc from swelling freely and allows the disc to develop its osmotic pressure. The tissue starts to swell because ions flow out and water flows in. However, when the vertebrae are removed the tissue can swell freely. The nucleus especially because the ion concentration is higher than in the Annulus.
