In this paper authors present methods that can be used to improve efficiency of solidification process simulations conducted with use of the Finite Elements Method. The properties of many core architecture, such as graphics processors (GPU), are taken into consideration. This paper describes problems related to building system of equations on graphic cards. A two-step method of building the linear equations system for the solidification process was described. This method is designed for a specific properties of graphics processor. The properties that are taken into account are data transfer and graphics card memory size. Using described method to perform simulation of solidification process could decrease time of computation on GPU as well as CPU.
