What is it about?

Two steps are taken to achieve an integrated improvement of the elasticity-based mesh deformation method: first, the robust power parameters and the weighted parameter are introduced to enhance the robustness of the basic elasticity equation. Second, a mesh quality parameter is implemented to prevent the large distortion of the poor elements and this parameter is added to the elasticity equation as a constraint.

Why is it important?

The integrated improvement of the elasticity-based mesh deformation method does not only allow for the selection of suitable robust parameters to achieve more robust deformed meshes but also reduces the distortion of the poor elements near the moving boundary, even when the deformation is severe.

Perspectives

Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. I hope this article will allow researchers explore more complicated or unresolved unsteady flow field problems with moving or deforming boundaries.
