A new finite difference methodology has been developed for the numerical solution of partial differential equations arising in multiphysics applications on complex domains. The mapped-stencil finite difference method presented in this research is based on a unique transformation which maps each 7-point stencil in the 3D physical domain to a generic uniform computational stencil on which the differential equations are discretized. The mesh can be of any type, or the domain may be covered by a cloud of points, as long as a stencil connectivity can be established for each node in the mesh. Hence, the restriction of finite difference methods to structured grids is eliminated. This new formulation is validated against analytical solutions and other simulation results, for a variety of unsteady and steady problems. © 2020 American Institute of Physics Inc..
