FLOW-3 D® is a unique computational fluid dynamic program that was developed by Flow Science inc. in US. FLOW-3 D® has a full Navier-Stokes solver based on the FAVOR® (Fractional Area Volume of Obstacle Representation) finite difference scheme. The true VOF (Volume of Fluid) algorithm is in-corporated into FLOW-3 D® that provides the reliable free surface flow analysis. FLOW-3 D® has a variety of physical models. Therefore FLOW-3 D® is used in the wide range of industrial area including the inkjet or the coating. In this paper the feature of FLOW-3 D® and the direct computation of dynamic contact lines, the application examples for the coating are described.
