Abstract:This thesis presents the theory and implementation of a parallel software package for transferring data between non-matching planar interfaces. The method used for transferring data is based on the common refinement technique developed by Jiao and Heath in 2004 [X. Jiao and M.T. Heath. Common-refinement-based data transfer between non-matching meshes in multiphysics simulations. Int. J. Numer. Meth. Engng., 61:2402-2427, 2004]. A modification is made to the base method that provides strict conservation between participating meshes. It is shown that the modified common refinement based method provides accuracy that is equivalent to the standard method while strictly enforcing the form of conservation that is desired. A parallel implementation of the data transfer method is shown to have good scaling when the number of unknowns per processor exceeds 1000. Solving the linear system is the primary aspect of the data transfer process that determines the scalability of the method.
