Hi all, I am looking at the online documentation for the mdp option 'deform' and this whole set of numbers " a(x) b(y) c(z) b(x) c(x) c(y) " is a bit unclear in terms of the notation. Say, I want to gradually dilate the box only along x and y at equal rates rx and ry, nothing for the rest of the components. Is it then 'deform rx ry 0 0 0 0' ? Thanks, Alex
