Hey Amir,

It seams that you have two faces in the same place which are comfusing the meshing process. From the Geometry command botton, choose Faces and then choose Connect (second top button from the right). Choose the whole domain and apply. This will get rid of any unwanted faces. Meshing should be smooth now.

All the best

Hi Amir,

It seams that you are trying to use the Cooper option under Hex/wedge to mesh a volume. If so, try meshing one face, and then, for sources, choose the meshed face and the one opposite to it.

Good luck

Ahmad

Hi Are you using Cooper meshing scheme??? Did you mesh the lower geometry perfectly or are you just applying default options. I hope geometry is 3D as you have stated it is complex. how did you create it?send some more details about the error. bye ms

Dear Amir

How did you solve this problem of "two sets of source faces which form natural starts for the projections could not be found"
