[ICEM] 2D to 3D block by rotation

Thanks; so you mean the main remedy in such situation is to ply with vertices and edges regaridng to each other?

Aligning vertices and edges is the key to good blocking, besides the good blocking topology. But I found some new problems, which are related to how we apply the o-grid. I guess I should apply O-grid for boundary layer mesh first and then the o-grid for the pipe(both inner and outer).

I myself use block Extrusion for inlet pipe!

me too. After that I applied the O-grid around the pipe inside the main domain and then inner o-grid for the pipe all way to the bottom wall.

Hi, all.
I´m new in ICEM. I read ICEM tutorials and tried to mesh a simple 3D axisymmetric geometry that is shown in Figure 1. I want to mesh this geometry using 2D to 3D blocking method. Therefore, I meshed the 2D block that is shown in figure 2 and tried to rotate this 2D block to mesh the 3D geometry. The problem is ICEM cannot mesh this geometry using the mentioned method (Figure 3, 4).
Where do you think I am wrong?

Associations?

I have associated 4 vertexes to 4 points that exist on the 2D block corners and 4 edges to 4 curves of the 2D block. based on the some sections of tutorial I thought that face to surface association is not necessary in this case, but it is. Thank you Antanas.

did you follow the procedure in youtube tutorial ?

Hi Sijal,

Yes, It was not helpful.
