Meshing problems

Hello,

I am trying to mesh a very complex and big model, with duct with very different dimensions (i.e. an inlet duct is a rectangular inlet of 6x2 cm and another duct is a circular tube with 4 mm of diameter). 

I use a surfaces control, a BLs controls and then I start the volume mesh. I made some test with different size of the mesh and everytime the volume mesh process fails with many warnings and errors such the followings:

  • WARNING: 1 duplicted elems excluded. It may cause association problem later.

  • **Warning: no BL/fluid volumes meshed, BL contouring skipped.

  • topo err: elem882024->side0: wings=3, non-baffle-wingss=3 (no error highlighted) Meshing failed.

  • Volume Mesh Failed

But if I don't use a BL controls the mesh process will be fine and the model can start a simulation. How can I solve the problem?

I attach the mesh log.

Thanks a lot in advance.
