An efficient radial basis functions mesh deformation with greedy algorithm based on recurrence Choleskey decomposition and parallel computing
TL;DR: A parallel mesh deformation method based on parallel data reduction and displacement interpolation is proposed and the proposed recurrence Choleskey decomposition method (RCDM) can decrease the computational cost of solving interpolation weight coefficients from O ( N c 4 ) to N c 3 , where N c denotes the number of support nodes.

Mesh deformation based on radial basis function interpolation
TL;DR: A new mesh movement algorithm for unstructured grids is developed which is based on interpolating displacements of the boundary nodes to the whole mesh with radial basis functions (RBF's), which can handle large mesh deformations caused by translations, rotations and deformations.

Modelling of fluid–structure interactions with the space–time finite elements: Solution techniques
Tayfun E. Tezduyar,Sunil Sathe +1 more
TL;DR: The aspects of the FSI solution process enhanced include the deforming‐spatial‐domain/stabilized space–time (DSD/SST) formulation, the fluid–structure interface conditions, the preconditioning techniques used in iterative solution of the linear equation systems, and a contact algorithm protecting the quality of the fluid mechanics mesh between the structural surfaces coming into contact.
