So I couldn't solve my problem after trying to volume mesh improving techniques. But I would like to know how to use body of influence in Fluent Mesher.
1- I have a rectangular domain which has a wing in it. I have another body inside the domain which is used as BOI.
2- I removed the wing from the domain with boolean in Design Modeler. I didn't remove anything from the BOI. I didn't use share topology in DM either.
What are the steps I should follow in order to create my mesh properly? I have the sizings I need and I feel like I'm making some other mistake like choosing a wrong method for BOI in Fluent Mesher. I use the same sizings in Ansys Mesher and it works just fine. When I use those sizings in Fluent Mesher, the mesh looks good and it passes quality checks but it gives terrible results (it diverges in 100 iterations or so). I must be making a fundamental mistake here within Fluent Mesher. Could you help me find the problem please?
