OpenFOAM Adaptive Mesh Tutorial: Modifying the Dam Break case for AMR

Consider supporting me on Patreon:   / interfluo  

A introduction to adaptive mesh refinement (amr) in openfoam. amr can be used to refine the mesh in areas of interest described by some user specified parameter. In this case I am refining the mesh at the fluid interface. amr promises to give the results of a very fine mesh while maintaining calculation times for a much coarser case.

Although amr is extremely promising, it does have potential drawback. The computation associated with adapting the mesh is quit intensive; in some cases this cost does not offset the benefits from having fewer cells. It is also more difficult to decompose the domain in order to parallelize the computation.

Even with these downsides amr is a promising technique with vast potential benefits. I will continue to explore amr in future videos, stay tuned!
