Many problems in computational mechanics involve one or more boundaries that are interfaces between different materials, including fluid-fluid, solid-solid, or fluid-solid.  Problems in this class present many difficulties for numerical solution techniques since they introduce moving boundaries and consequently evolving geometries whose location and topology is unknown a priori.  In this Minisymposium, we will provide a forum for researchers to meet and share ideas and experiences in this challenging area of computational mechanics.  We seek submissions on all aspects of this problem: theory, formulation, analysis, and applications.  Presentations including numerical verification and experimental validation are encouraged. We also encourage papers on manufacturing flows and flows with free surface flows with non-Newtonian fluids.

Methods include, but are not limited to:
•    Level set and volume-of-fluid
•    Arbitrary-Lagrangian-Eulerian (ALE) methods
•    Sharp and diffuse modeling of interfacial zones
•    Deformed geometry remeshing
•    Fictitious domain methods
•    Particle methods
•    Embedded boundary conditions
•    Cut mesh methods

Application areas include, but are not limited to:
•    Manufacturing flows
•    Fluid-solid interactions
•    Multiphase flow
•    Dynamics reaction fronts
•    Low capillary flows
•    Surface tension formulations
•    Interfacial mass transfer
•    Melt/solidification front modeling
•    Bubble and suspension dynamics
•    Mold filling
•    Dynamic wetting lines
•    Suspension and emulsion rheology
•    Polymer extrusion and mixing
