Hi,
It is not the first time I encounter this problem. I am meshing multiple annular hollow pipes surrounded by a fluid domain. FLuid flows internally and externally to the pipes (attached figure). Fluid enters from a plenum, then it is divided into two flows: internal (to the pipes) and an external flow until the other plenum is reached (the outlet plenum). The attached figure is the first interface that the fluid meets when facing the multiple annular pipes. Right there I am getting this odd mesh that has some of the surface elements belonging to one face and the others belonging the opposite face. How can I have just only one surface entire meshed? I would really appreciate some enlightenment here. |

you need to make sure the nodes, edges and faces of the blocking are associated to the correct geometrical points, curves and surfaces

I don't know. I would do it where necessary.

Thanks. I have associated and it works better. However, I am still getting errors due to the interface creation. Now I have to associate both sides to this surface, but it is an internal wall. Once CFX-Pre notices a wall on one side it requires the other side to be in the same size, but it is not. The fluid face is bigger than the tube face. Have ever you encountered such a problem?
