Abstract
The essential interface algorithm has been developed in the numerical calculation. We define a position and a few physical quantities on the interface to calculate more accurately. To solve the position and physical quantities on the interface with Lagrange scheme, the present scheme solves the fluid equation of Lagrangian description. Time step is progressed by using Low Storage Runge-Kutta (LSRK). In the hypervelocity flow, a better result has been obtained.
