1. 1. A new finite element method for elliptic interface problems

   Författare :Alexei Loubenets; Björn Engquist; Gustav Amberg; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical analysis; Numerisk analys;

   Sammanfattning : A finite element based numerical method for the two-dimensional elliptic interface problems is presented. Due to presence of these interfaces the problem will contain discontinuities in the coefficients and singularities in the right hand side that are represented by delta functionals along the interface.

3. 2. An Immersed Finite Element Method and its Application to Multiphase Problems

   Författare :Alexei Loubenets; Björn Engquist; Michael Shelley; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fluid and plasma physics; applied mechanics; computer science; Numerical analysis; Numerisk analys;

   Sammanfattning : Multiphase flows are frequently encountered in many important physical and industrial applications. These flows are usually characterized by very complicated structure that involves free moving surfaces inside the fluid domain and discontinuous or even singular material properties of the flow.
