How to join blocks in Ansys-CFX?
 
Hi,

I generated grids in Gridgen, and import the gridgen file into ANSYS-CFX. I have several blocks for the meshes, and all blocks are together. However, there are several boundaries there. Right now, I want to join those blocks as one, and delete those boundries. How can I do it? Please help me.

are the nodes one to one?

Yes. All nodes are one to one, and blks are all well matched. Thanks.

You can merge blocks together when you import into CFX-Pre. Have a look at the import options.

Thank you so much.

Hi ghorrocks,

Do you mean interface? I tried to interface those boundaries, but I could not run the solver. I have eight interfaces. When I run the solver, errors came out. Thank you

No. When you import the mesh into CFX-Pre you can make it merge neighbouring blocks where the nodes are within a defined tolerance. Then CFX-pre merges them.

If they are not merged then you need to consider using interfaces to connect them.
