[ICEM] merging two type meshes

feizaghaee · June 20, 2013, 19:49

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 ???

feizaghaee · June 21, 2013, 10:33

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?

feizaghaee · June 24, 2013, 16:59

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