[ANSYS Meshing] Meshing a loop

Dinu · October 23, 2021, 14:47

Hello,
I have a project where I have to mesh room with the inlet and outlet connected with a loop outside the room geometry. Does anyone have any suggestions where you use only one material point?
Thank you!

Without full understanding what you need, I can provide a simple suggestion:

1. Simply set your inlet conditions based on your outlet conditions. Temperature and other scalar values can use massFlowAve(scalar)@Outlet when defining the inlet conditions. You can modify the inlet conditions as required if that flow is heated or mixed with other flows before returning to the inlet.

Thank you for your reply!
I have attached a picture of the model. I want to mesh the entire geometry but with one domain. Although i have done it with interfaces i'm not sure whether i can put the inlet and outlet as the interfaces. And when i load the mesh ino CFX, it shows inlet shadow and outlet shadow in boundary conditions. I want to run a simulation with just one fluid

Either use interfaces, or combine the bodies into one multibody part in design modeler or other CAD interface.
Then it will mesh with conformal nodes at the interfaces.
Of course you could just combine the two bodies into one body as well in the CAD program.

What is in the loop?
