Abstract
The concurrent-type hybrid simulation scheme, in which a total system is divided into sub-systems and a proper numerical method is applied to each of them, has attracted much attention in recent years. We have developed a visu alization package "Akira" to be applicable directly to analyses of various hybrid simulation results composed usually of both atomic (particle) and volume data. Akira can display the simulation results in impressive manners, for example, by showing both atomic and volume data with colors relating to the values of physical quantities, and by showing the traces of selected atoms. A user can easily create sequential image-files for the time-evolution. Akira is written in Java with OpenGL; hence, it is executable on various platforms. The source code of Akira is open for the public along with its developing documents. The characteristic functions of Akira are explained with demonstrations.
