[GAMBIT] cyclone inlet mesh

jamalf64 · June 1, 2015, 05:51

Hi dear all
I tried to mesh cyclone inlet but I couldn't mesh that due to skewness>0.97
What I do?
Please help me.
Thanks in advance

Try to add some more portion of cyclone main body into inlet to avoid sharp edge.

Thank you for your response
In your opinion I must change in geometry? (If I understand truly)
This change may effect on fluid flow patterns. Am I right?

yes, as bharath mentioned you need to modify slightly you geometry.
Your problem lies on vertex 22 and vertex 15.
Line and circle are tangential which generates sharp angle.
I would sweep face formed from vertex 13; 9 ;15 and 22, with very small vector in the direction normal to this surface.
