The available Eulerian elements are the three-dimensional, 8-node element EC3D8R and the three-dimensional, 8-node thermally coupled element EC3D8RT. Two-dimensional simulations can be approximated using a
one-element thick mesh or a wedge-shaped mesh with appropriate boundary
conditions. The Eulerian mesh is typically a simple rectangular grid of
elements that does not conform to the shape of the Eulerian materials. Complex
material shapes can be represented inside this mesh using a combination of
fully and partially filled elements surrounded by void regions.
