Every non-trivial problem in hydrodynamics involves boundary conditions, and/or driving by external or internal forces. From a computational point of view this implies the need for both a flow solver, and a method to couple the flow to the boundaries and/or forces. The conceptually simplest case is a non-moving rigid boundary that limits the flow of a Newtonian fluid, commonly referred to in the engineering literature as "fluid-structure interactions". More complicated cases arise when the boundary can move, or the solid is elastic, or the fluid is non-Newtonian, or combinations of these. Furthermore, the fluid may undergo phase separation, and at small length scales thermal fluctuations need to be taken into account - a regime that is typical in the Soft Matter domain. Blood flow, to just mention one well-known example, exhibits many of these complexities.

Many methods have been developed to deal with the resulting computational problems, using several different approaches. In the field of Soft Matter the host of available methods is particularly broad. This meeting aims at bringing together researchers with different and complementary backgrounds, ranging from physicists to chemical engineers and applied mathematicians, who are experts in their respective fields. The goal is to promote the efficient application of advanced numerical methods through a deep understanding of the physical and mathematical background. It is anticipated that a discussion of the relevant questions will lead to a comparison of observations, a sharing of procedures, and foster new collaborations among a multidisciplinary group of scientists and engineers working on an important contemporary problem.

The format of the meeting is planned as a two-day tutorial, followed by a three-day workshop.
