| Research Abstract |
We developed a GPU-based code for impact calculation from CPU-based code. We added some new components to our code in order to solve the equations quickly. Finally, calculation speed becomes 30 times faster than the previous CPU-based code. We applied our code to several problems. We performed very high-resolution simulation of the moon forming impact, and we found that the effect of angular momentum transport was week. We conducted cooperative research on impact simulation with experimental lab.
