The ALE (Arbitrary Lagrangian-Eulerian) framework allows for a fully-coupled fluid-structure interaction approach when modeling such complex behavior as a high explosive detonated in contact with a reinforced concrete column. Structural elements, such as beams and shells, have also been implemented for structural applications.

This is an example of a fully-coupled fluid-structure interaction blast effects simulation. This simulation shows a small high explosive charge detonated in contact with a reinforced concrete column. The orange material is the high-explosive products. Completely damaged concrete is shown in red and undamaged concrete is shown in blue.
