000009229 520__ $$2eng$$aModeling of fresh concrete flow is interesting problem from both theoretical and practical point of view and its application to self compacting concrete casting simulations is a subject of active research with important practical aspects. Practical importance is especially in application to self compacting concrete, which is highly actual. It is usually modeled in eulerian description of motion as a problem of two immiscible fluids (concrete as a Bingham fluid and air as a newtonian fluid). Due to different physical properties of these fluids, there are discontinuities of velocity and pressure fields at the interface. In this paper, the eXtended Finite Element Method (XFEM) is used allowing the standard FE approximation space with tailor made functions across the interface to resolve the discontinuities.
