[ICEM] Improve hexa mesh quality and determinant -- CFD Online Discussion Forums

January 29, 2019, 13:47	Improve hexa mesh quality and determinant	#1
Ramon Quiñonez New Member José Ramón Quiñonez Arce Join Date: Oct 2017 Location: Leeds, UK Posts: 17 Rep Power: 8	Hello, I am currently working with the mesh of a flame stabiliser in a quarter of a combustion chamber. I am considering only hexahedral elements, and a annular feed at the outlet face of the contraction. I have been working with this geometry in the past producing sensible meshes, but this one has a simulated weld at the inlet of the contraction, so i just added more ogrids to the mesh, and the quality is very bad, and also the determinant. Could you please help me with some tips on how to improve my mesh? I attach some photos, they show my current geometry and mesh, as you can see I have created some ogrids for the annular feed and the simulated welding. 1.jpg 2.jpg 6.jpg 7.jpg 9.jpg Many thanks!
