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.

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.

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.
