Dam Break with Adaptive Meshing

Many interesting engineering problems involve the mixing of two separate immsicible fluids. The volume of fluid method is a good way to track the interface between the two (or more) fluids. A common test problem for this approach is a transient "dam break". In this scenario, the fluid retaining wall is suddenly removed and the transient flow topology is solved for.

To improve the computational time, a coarse mesh is used. To improve the solution, adaptive meshing is used to refine the mesh along the fluid-fluid interface, and coarsen it away from it. The results to the left show the fluid-air interface as it evolves over time. The model was created in Design Modeler, meshed and solved with Ansys Fluent, and post processed using CFD Post.
