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.

TL;DR: A new Mesh Deformation method based on Cartesian Background Mesh (MDCBM), where the Cartesian background mesh is deformed with radial basis functions (RBF) and the displacement of Cartesianbackground mesh is algebraically interpolated onto all meshes in the computing domain.

TL;DR: In this paper, a multi-body separation grid overlapping method and system suitable for parallel processing is presented, which comprises the steps of refining surface elements of surfaces of grid blocks, marking edge units of the grid blocks; storing the edge units in a classified manner; according to the stored edge units, judging whether grid blocks of different objects have an overlappingposition relationship or not; and performing holing and hole boundary backtracing for grid blocks with the overlapping position relationship, of the different objects, and performing contribution unit search for an overlapping boundary, thereby realizing multibody separation grid

TL;DR: In this article, a method for rapidly matching between unstructured boundary surfaces and grid surfaces is utilized, so that the grid boundary conditions of unStructured grids in Tecplot form can be rapidly mapped to corresponding boundary surfaces of infield body grids, and the computer time can be effectively decreased.

TL;DR: In this paper, an isomerization program interaction method based on file names in the Windows system has been proposed to avoid reading and writing conflict, and correct interaction is guaranteed by using file names.
