[Solution]

For large mesh deformations with the ANSYS Fluent adjoint solver design tool, it is possible that the mesh quality deteriorates up to a point where the flow solution is no longer accurate enough. If you have a tri (2d) or tet (3d) mesh, you can use the dynamic mesh capabilities of ANSYS Fluent to improve the mesh quality in between design iterations. The attached document describes the necessary steps and possible pitfalls of using dynamic mesh settings dur-ing design iterations, including possibilities to automate the process. Prior knowledge of the ANSYS Fluent moving/deforming mesh (MDM) capabilities is useful but not re-quired to follow this document.
