In this work, an object-oriented geometric engine is proposed to solve problems with discontinuities, for instance, material interfaces and cracks, by means of unfitted, immersed, or enriched finite element methods (FEMs). Both explicit and implicit representations, such as geometric entities and level sets, are introduced to describe...

The Couinaud classification of hepatic anatomy partitions the liver into eight functionally independent segments. Detection and segmentation of the hepatic vein (HV), portal vein (PV) and inferior vena cava (IVC) plays an important role in the subsequent delineation of the liver segments. To facilitate pharmacokinetic modeling of the liver...

This paper presents an efficient computational model for the simulation of fully coupled two-phase flow in a deformed partially saturated formation. Focus is placed on modeling the flow of a CO2 plume in a porous medium. The numerical procedure is based on coupling between the Level-set method (LS) and the extended finite element method (XFEM)....

There exist many examples of aircraft incidents in which the pilots have successfully used the remaining control authority over an aircraft to save the airframe and its passengers and cargo from apparently hopeless failure conditions. Unfortunately, the opposite is also true. Several accidents happened in which the crew was not able to save the...

The simulation of free surface flow is a computationally demanding task. Real life simulations require often the treatment of unstructured grids to capture the complex geometries and the use of parallel supercomputers for the efficient solution. For that aim, we have developed an efficient parallel free surface flow solver based on a full...

We present a new Cartesian grid method for the computation of incompressible viscous flows in irregular geometries. The irregular boundary is implicitly represented by its signed distance function (the level-set function) and, by using level-set calculus tools, we are able to preserve the Cartesian structure of the discretized Navier-Stokes...

The field of microfluidics has dramatically improved over the last decade: it enables the transport of minuscule amounts of fluid (nanolitres) through channels the diameter of a single human hair. This miniaturization is increasingly employed to build a wide range of technological devices for example, genome sequencing or using microdroplets as...

An eulerian approach for fluid-structure coupling is presented for generic fluid-structure coupling an elastic body with an incompressible fluid. Fluid-solid interfaces are captured by a level-set method. The main features of the method are its simplicity, and its natural control of mass and energy. We are indeed able to prove an energy equation...
