| description | The invention belongs to the field of aircraft design and provides a quick interpolation method for a multi-block structure grid on the surface of an aircraft. The method comprises the steps of 1, reading information of all grid blocks, separately forming an array for each grid block, and recording all grid coordinate data and flow field parameter data in an array form to form grid information; 2,finding out maximum value and minimum value information of each grid block in X, Y and Z coordinate directions by a program to form a coordinate envelope range of the grid block, and adding the coordinate envelope range to numbered grid block information; 3, extracting coordinates of data points as needed, retrieving envelope information of each grid block according to numbers, judging whether demand points fall into a cuboid space range of each block or not, and if the blocks are in the envelope range, recording serial number information of the blocks; 4, performing statistics on a quantityof the blocks in the envel |
