The domain of the 3D Multi Material Euler (MME) solver can be filled with material and initial conditions using a single connected surface body in combination with a filling direction. The filling direction is defined by the direction of the z-axis of a local coordinate system, which is scoped to the Eulerian filling surface. To be used as a filling coordinate system, the origin of the local coordinate system should not coincide with the origin of the global coordinate system.

The extruded volume of the Euler surface body in the z-direction of the selected local coordinate system inside the 3D Multi Material Euler (MME) domain will be filled with the material and initial conditions of the surface body.

The extruded volume will extend to the boundary planes of the 3D Multi Material Euler (MME) domain.
