interpolation from cell center to vertices

August 14, 2003, 17:13

hi folks. i have a 2d domain with structured grid. in my program, all variables are stored in the cell center. in order to display the results in a general purpose post-processor, i have to interpolate these variables to the cell vertices. any suggestions or reference books? thanks!

HI, Some codes ( like FLuent ) have different calculation and post-processor method. These method are Node-based and Cell based-value. thomas

I think the best way is to use multilevel B-splines. They work very well and fast. For details see original paper http://www.postech.ac.kr/~leesy/ftp/tvcg97.pdf
