Abt: Moving wall boundary condition.
 
I am solving a fluid-structure interaction. The fluid flow is made by underwater explosion so the Euler fluid equations are solved.

In coupling between the fluid and the structure, the moving wall B.C. may be necessary. So, I imposed

U(nx+1,:)=-U(nx)+2*U_wall.

However, this B.C. showed some nonphysical behavior near the wall.

Does anyone know how to define moving-wall B.C?
