We present a modified finite element method that is able to approximate interface problems with high accuracy. We consider interface problems, where the solution is continuous, its derivatives however may be discontinuous across interface curves within the domain. The proposed discretization is based on a local modification of the finite element basis which corresponds to a fitted finite elemen...

We use Brownian Dynamics (BD) simulations and continuum models to study the microstructures and mechanics in the colloidal film drying process. Colloidal suspensions are compressed between a planar moving interface and a stationary substrate. In the BD simulations, we develop a new Energy Minimization Potential-Free (EMPF) algorithm to enforce the hard-sphere potential in confined systems and t...
