Can you show it with pics? because I am not getting the concept of four blocks. There are initially seven blocks. One is solid, two are in parallel to solid block and touching the cone, two other blocks are on top of these two blocks and other two blocks are in the front domain.

I mean get rid of those two blocks that touch the cone. Only keep 4 blocks, 2 in the front and 2 at the back. make those 2 blocks at the back larger enough so that they can take the place of those block that touch the cone and keep the original domain shape. Thank you

Best Regards

No. Because on these two blocks we are applying the Y-Grid. May be this is possible with circular domain

Hello Far,

I am facing a similar issue with a slightly more complex problem, image attached. Can you kindly suggest how to improve quality on this one? I am getting negative values of determinants in only one of the six quarter o-grids I have made for the streamline body on which the props are mounted.
