merging two type meshes
 

hi all. I'm meshing a channel. but I can't merge the in the interface. I attached a picture of these two meshes. I was wondering if somebody help me.

merging two meshes works only for 3d... can you block everything ???

the mesh on the left hand was generated by blocking and in right part mesh was generated by extrusion of quad dominant surface mesh. I found that the interface between two type of meshes doesn't include any nodes of meshes. when i use tetra mesh instead of extrusion of surface mesh nodes of tetra mesh are located on the interface but nodes of hexa meshes aren't.
how can I place nodes on the interface to merge the?
thanks in advance

under the edit mesh tab, there is an icon for merge nodes, but then again i don't recommend that method. why don't you block everything

thanks for your reply. only nodes of right part of the mesh are located in the interface. I can't merge nodes. I don't block everything because of geometry. the weir in this channel has various curvature radius. if I want to block everything, should I use multiblock?

Not multiblock!!! Simple hexa blocking will do the job. It should not difficult to make the blocking for 2d case.

thanks Far. I made a big mistake. I solved it.thanks a lot.

mistake related to merging? how did you solve it?

Yes. It was related to merging. I didn't create body in both side of interface.
