Qi Sun’s paper entitled, Improving the Robustness of the Immersed Interface Method through Regularized Velocity Reconstruction, which is co-authored by Amin Kolahdouz, has been accepted for publication in the Journal of Computational Physics.
This paper introduces a stabilization strategy for the immersed interface method that eliminates a restrictive mesh factor ratio requirement by using a Tikhonov-regularized velocity interpolation operator. The new formulation preserves accuracy while allowing the structure mesh to be much finer than the fluid grid, enabling stable and efficient simulations of complex fluid–structure interaction problems that were previously computationally prohibitive.
Congratulations, Qi!
