hi guys !! I hope you are doing good. I am working on a two domain problem of conjugate heat transfer between fluid with certain velocity and solid domain as pipe thickness. I have attained mesh quality above .5 but the problem lies in fluid domain. THE solid domain mesh is ok but when i check the fluid domain mesh it shows some surfaces not proper meshed. when I open it in cfx I can’t define proper boundary condition because of that empty windows or slots in fluid domain. I am using ICEM blocking method to create unstructured mesh. Please refer to pictures for better idea. solid domain is made hidden only fluid domain is shown in pictures. any suggestion or methodology of problem solving ??? thanks in advance Attachment 520502.jpg

yes i have used o grid and also modified o grid in the fluid domain with different edge distances

Maybe my experieence for blocking is not so high. However, I try it and feel it seems more diffifcult to control with complicated geometry. I recommend to generate 2 different meshes and using non-conformal or you should try other generation sofwares.

kindly if you can explain your answer in a bit detail i am student working on my research i am not professional can you guide me how to generate 2 different meshes and using non- conformal method and also which software for meshing you can suggest

@Abdullakhan: If you still want to try blocking like that, I suggest you to be sure about association edges along tube (not only cross-section) |

You have bad topology. Unnecessary and inconsistent surface splits, different curve directions (see first image). It's hard for mesher to decide how they all should be connected. I worked a little on your geometry and got good mesh. (see second image).
You can download my workbench 17.2 project here. |

i cant open the work bench file you sent i am using ansys workbench version 15 if you can email me the mesh file 08pwmec2782@gmail.com more ever what you suggest how can i fix the problem how can i improve typology,curve directions and make it consistent surface split i design the geometry in PRO -E i am unable to design it in ansys design modeler because of the sweep didn't work in the second plane perpendicular to the first plane it couldn't sweep all at once upload the mesh file file only so that i can check and see if i can proceed future i am attaching my geometry dimension if you can model it for me ???
