CIP — Toward an Ultimate Goal to an Universal Solver for Gas, Liquid and Solid —

Various numerical schemes have been proposed to solve the dynamics of gas, liquid and solid, separately. In many cases, however, we need to solve the interaction among these different materials. Many problems will arise for this computation to be put into reality. For interaction between liquid and gas, we need to solve compressible and incompressible fluids simultaneously. This means that the scheme must be free from CFL condition of sound wave and all speed of sound wave must be treated.
