Store-carriage, pylon, fuselage interaction problem for modelling part of a fuselage of a fighter aircraft in low Mach number flight is studied by solving the full Navier-Stokes Equations numerically. A Finite Element Method (FEM) with an explicit time marching scheme is used for the solution. An artificial viscosity, equivalent of streamwise upwinding, is implemented while obtaining the velocity field. The pressure field is determined via an auxiliary potential function obtained with an accelerated iterative solution of Poissons' equation. Comparison of the pressure distributions and aerodynamic force coefficients obtained by the code for various test cases has validated the code. Therefore the code is utilized for more complex flow predictions.
