Hello everyone, I’m a beginner in ANSYS Fluent and I’m working on solar thermal collectors.<\/div>\n
I drew the geometry to have these (9) parts: (air gap, pipe, water volume, weld joint, absorber, air duct, and 3-air domains) as shown in the picture below. Also, I made these parts as one part (form a new part). <\/div>\n
In meshing, I generated the mesh directly after that I began to modify it by trying several options (sizing, inflation,…., etc.) as you can see in the picture. But, still can’t reach so good mesh quality (skewness & orthogonal).<\/div>\n
My questions are:<\/div>\n
1- regarding the geometry, is there any difference if I make an extrude for a surface to create a fluid domain? or should all fluid domains created by making volumes? <\/div>\n
2- regarding the mesh, the tick sign in front of the geometry parts (see the red rectangle in the picture) is changing every time I make meshing, what is the reason?<\/div>\n
3- I’m asking you to help me do the best mesh for my case. Which mesh method and sizing should I select to enhance the mesh?<\/div>\n
 <\/div>\n
Thank you.\"\"<\/div>\n","protected":false},"template":"","class_list":["post-326567","topic","type-topic","status-closed","hentry","topic-tag-3d-geomertry","topic-tag-extrude","topic-tag-fluid-volume","topic-tag-meshing"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
