Outline of Final Research Achievements

The purpose of this study is to expand the computational capability of the phase-field model by applying the GPGPU technique to its numerical code. The GPGPU technique is applied to both dilute and regular solution alloy systems.
In the case of the dendrite growth in binary dilute alloy system, the calculation speed is increased only several times by using GPU. On the other hands, in the case of ternary regular solution alloy system, the computational speed is increased about twenty times.
