Abstract
To reveal the pysical mechanism of the heating and acceleration of the solar wind, we have conducted for the first time a three-dimensional MHD simulation of the solar wind.

Reasons for using JSS2
We need a large amount of calculation resource to debug and to improve the parallelization efficiency. JSS2 is used for code development and test calculation.
Achievements of the Year
We have developed a numerical code for three-dimensional MHD model of the solar wind including the divergence B cleaning and a new solver for fast thermal cnduction. It took a long time to debug and to stabilize the code. We have run the code with another super computer and suceeded in simulating the solar wind for the first time.
