WebJan 29, 2024 · You define a Transfinite Line between certain points, in your case between the corner points of your large rectangle. While doing so, you can specify how many nodes should be included on this line. If you choose the same number of nodes on the opposing lines of the rectangle, you should be doing fine. WebI know the thickness of the first cell from the wall (dx0), the length of each line (L), and the progression I want (r), so when I’m using Progression I can calculate the number of nodes to use as N = log (1+ (L* (r-1))/ (dx0)) / log (r) – 1. Then I can set the appropriate lines to Transfinite and assign them N Using Progression r and it ... jb08-1u-pr-bk
