[ICEM] Angle below 18 degrees solution?

rupak504 · November 17, 2019, 23:25

hi,

I was meshing a bottle shown in Fig. 11.11.png I had used O-grid 12.png 13.PNG. I am getting angle below 18 degrees mostly at the bottleneck14.PNG 15.PNG. Kindly suggest some solution.

regards

Would it not be easier to create a 2d-mesh and extrude/rotate it about the axis?

That's one way to do it, but i wonder, would that solve the problem. Anyway i will try that first and see.

I never tried it because my geometries are usually not symmetrical, but with this I would definitely try. I would be curious to see your results there.

Please create a screenshot of the cross section

Use "scan planes" to create a section and show us the corner region in more detail.

You'll find scan planes in the context menu of premesh.
