For the purpose of numerically analyzing the phenomenon from cavitation to erosion, we have introduced a new function of simulating solid phase benaviors to the CRIMSON code. The based code, CRIMSON, employs a finite-volume method combined with the high order and flexible interpolation scheme, CIVA, and enables unified solvers of two kinds of fluid behaviors, liquid (incompressible) and gas (compressible), by the algorithm of TCUP. The imptroved CRIMSON code can achieves gas-liquid-solid unified analysis. With the code, we numerically analyzed the cavitaion erosion of stainless steel by the micro jet from collapsing bubble in water and compared the results with the past study. Our approach is the two-way coupling between fluid and solid, can produce the more realistic solution.
