“…Examples of generic co-simulation couplers include e.g. MpCCI (Joppich and Kürschner, 2006), Open-PALM (Jaure et al, 2013), and CHIMPS (Schlüter et al, 2005). Since the standalone programs usually have been validated previously, the development process focuses on the implementation and validation of new coupling conditions.…”

We present a numerical method based on hierarchical Cartesian grids for the simulation of multiphysics problems, here in particular for the conjugate heat transfer between a fluid and a solid. The data structures developed for this simulation method allow to account for moving objects and are especially well suited for massive parallelization. The major problem of a suitable domain decomposition for a coupled fluid and heat conducting domain is solved by discretizing both domains on a joint hierarchical Cartesian mesh, where the individual cells can be marked according to the underlying physics, i.e. to be a fluid cell, a heat conducting cell or both. Individual solvers for the Navier-Stokes equations and the heat conduction equation are implemented which only operate on the Cartesian cells belonging to the fluid or solid subset of the joint hierarchical mesh. The solution strategy is validated against the analytical solution of the convective heat transfer between a heat-conducting solid flat plate and a laminar incompressible boundary layer. The applicability of the method for moving objects is then demonstrated by solving a conjugate heat transfer problem for a heated and moving cylinder in a laminar flow.

“…4. The calculation of structural node load based on MPCCI tools MPCCI tools can realize the coupling problem between multiple disciplines by proving a single subject simulation program [12] . The data can be exchanged between two or more FEM software by dividing the calculation into a number of step length, simplex data is transformed during each step and exchanged between two steps.…”

“…Examples of generic co-simulation couplers include e.g. MpCCI, 4 OpenPALM, 5 and CHIMPS. 6 Co-simulation approaches, however, struggle in modern supercomputers since computing resources are given to each program independently of the others and each program further partitions its computational domain independently as well.…”

Conjugate heat transfer of solid bodies is studied using two independent finite-volume solvers linked by surface-based coupling techniques. One method solves the unsteady Navier-Stokes equations of an ideal compressible fluid and the other method solves the unsteady heat equation within the solid. A hierarchical datastructure able to store multiple hierarchical Cartesian grids in a compressed format while implicitly maintaining the inter-grid connectivity even under adaptive mesh refinement is introduced. Its suitability for the operations required during multi-physics coupling are considered. It is shown that the data-structure delivers an efficient look-up of the connectivity information between cells of a given grid and between cells of different grids by performing the domain decomposition on this data-structure instead of the computational grids. Inter-node communication during the coupling step is avoided. The feasibility of this approach is demonstrated by studying the interaction of a stationary solid cube with a hot jet as well as the interaction of two heated moving particles in tandem with a cold fluid.
