Fluid flow simulations that involve deforming domains, in the presence of one or more moving boundaries or fluidfluid interfaces, continue to present unique challenges, and form one of the frontiers of computational science. Freesurface flows in particular involve the motion of the fluid interface which is unknown at the outset of the simulation. Thus, both the domain and the flow field are par...

This contribution is the first part of two papers on the Fully Eulerian formulation for fluid-structure interactions. We derive a monolithic variational formulation for the coupled problem in Eulerian coordinates. Further, we present the Initial Point Set method for capturing the moving interface. For the discretization of this interface problem, we introduce a modified finite element scheme th...

The direct numerical simulation of two-phase flows with interface capturing methods La simulation numérique directe des écoulements diphasiques avec les méthodes de capture d'interface écoulements macroscopiques dans lesquels les échelles de longueur et les vitesses sont grands.

This work considers a Stokes flow in deformable fracture interacting with linear elastic medium. To this end, we employ phase-field model to approximate the crack dynamics. Phase-field methods belong interface-capturing approaches which interface is only given by smeared zone. For multi-domain problems, accuracy of coupling conditions is, however, utmost importance. Here, interface-tracking are...

A study of undergraduate students learning to program compared the use of a physical interface with use of a screen-based equivalent interface to obtain insights into what made for an engaging learning experience. Emotions characterized by the HUMAINE scheme were analysed, identifying the links between the emotions experienced during programming and their origin. By capturing the emotional expe...
