Hi, Far. I saw you have finished the prim mesh in this geometry. Don't you mind sharing the method to generate prim mesh? And I have another question. I defined the 3 orginal outlets as 3 interfaces in fluent and creat the mesh interface. The interface zone 1 is interface 1,2 and the interface zone 2 is interface 3. Finally, the problem of the assigned intefaces have been solved. But when I ran the calculation, the error is: divergence detected in AMG solver: pressure correction. I tried to reduce the UDF, but it didn't work. Do you know the reason? And you told me to record the result from the extended outlets to original outlets, Could you give me some detailed information about this method, please? I will appreciate your help! Thank you so so much!

Regards,

Rong

No need to create the internal wall, this function is used when you have wall inside the domain and there is fluid on both sides of this wall. Which is not the case with you.

you are mixing up internal wall with interior.

It is really simple.
1. I just set the global mesh parameters.
2. Prism mesh parameters
3. In part mesh panel, tick the prism mesh for part, for which you want to grow the prism
4. In compute mesh panel >>>> volume mesh >>>>>>> select the prism mesh option as well and then compute mesh

Could you send me the project file? Because I did according to your setps but I failed. Thanks a lot!
