We have succeeded for the first time to simulate dynamic phase transition from metal to vapor. This success is due to the CIP (Cubic‐Interporated Pseudoparticle/Propagation) method that can treat solid, liquid and gas together and can trace a sharp interface with almost one grid. We report here the application to laser‐induced evaporation, in which aluminum is evaporated well after the laser beam ended and evaporation occurs with a large angle to the target normal leading to large debris. This process is analogous to the bombardment of high energ particles onto divertor plate. The scheme can be easily extended to 6‐dimensional space and has been applied to Vlasov solution in 6 dimensions. By this method, grid‐based Eulerian calculation in 6 dimensions becomes possible with higher accuracy and similar memory storage as the particle schemes.
