Hello everyone,

I am pretty new to ICEM and I am having an issue with the 3D-meshing of a Dimple as you can see in the picture. I was thinking that it would be best to mesh the dimple with an o-grid but I am having trouble connecting the generated o-grid to the H-grid of the surrounding domain. I tried it different ways but always end up getting bad cells (angle/determinant).

Do you have any suggestions how to mesh this geometry properly?

Thank you guys and best regards!

Hi R4z0rX,


your idea to use an o-grid is correct. The round part clearly needs one. That's already half of the solution!

If you inspect the result of your o-grid, you might observe that you transform from an arc-shape to a rectangular block.
With some abstraction the surrounding H-Grid is also transforming from a rectangular block to an arc. It could be considered the inverse problem of a tubular section.

The solution for that is also an o-grid.
Therefore, you need two o-grids within your blocking to compensate the tubular section transforming into the peripheral (rectangular) spaces.


So what you need to finish your initial blocking is probably just add another layer to your blocking and move the vertices that one layer of the o-grid is around the tube section, and the o-grid inside the tube (which you probably already have).
The geometric perspective i am talking about is the top view of your screenshot's perspective.


As a summary a drawing of what i mean:
