Abstract Scope	Using molten silver to infiltrate through sintered porous interlayers is a promising new technique to create strong brazes between steel and ceramics in solid oxide fuel cells. Estimating infiltration speed is needed for optimizing the fabrication process. In this work, a diffuse interface embedded boundary method known as the Smoothed Boundary Method (SBM) is utilized to facilitate simulations of fluid dynamics involving complex geometries. Using this method, the geometry is described by a continuous domain parameter, thus allowing the straightforward reformulation of the time-dependent Navier-Stokes equations in terms of this domain parameter. In this case, a mesh conformal to the geometric boundaries of the microstructure is not required and the numerical simulation process is greatly simplified. The direct flow simulation allows the calculation of the permeability of porous media, a property commonly used to predict infiltration speed. We use these calculations to investigate the infiltration of silver in porous microstructure.
