Hi,
The problem I am facing is that when i mesh the edge, the node does not follow exactly the edge line (not alligned). This creates negative volume when i mesh the face =(. Picture is attached with this post. I would appreciate it if any expert is willing to help =) |

your exact line, is the one with the nodes.
Indeed you describe your edge with more "resolution" than your topology line, which is a "simple" representation. I think your problem may come from your Aspect Ratio, you have very streteched cells (near walls)

I assume your first cell height (in the BL) is given because of y+, so you only have the possibility to add more nodes along your edge.
