Using CUDA Architecture for the Computer Simulation of the Casting Solidification Process

This paper presents a simulation of the casting solidification process performed on graphics processors compatible with nVidia CUDA architecture. The new approach shown in this paper allows the process of matrix building to be divided into two independent phases. The first is independent from the nodal temperature values computed in successive time–steps. The second is performed on the basis of nodal temperature values, but does not require a description of the finite element mesh. This phase is performed in each time step of the simulation of the casting solidification process. The separation of these two phases permits an effective implementation of the simulation software of the casting solidification process on the nVidia CUDA architecture or any other multi-/manycore architecture. In this paper the authors present the results of a computer simulation conducted on a GPU and CPU. The results of the computer simulations presented in this article were obtained with the use of authorial software (CPU-based and GPU-based).
