mesh error - "Mesh of linking face must be a structured quad mesh"

I set up a very simple plate vibration model. The plate is surrounded by PML except a small part with a rib on one side. Please see the attached model file. I want to use free Tetrahedral to mesh the plate (and the rib) and use swept mesh to mesh PML layer. However, I got error message "Mesh of linking face must be a structured quad mesh" at the face which between PML and the rib on the plate. I do not understand this message at all. Can anybody give some suggestions? Thanks

Hi

You have to mesh first the upper (or lower) plane with triangular elements and mapped mesh.

More Operations --> Free Triangular
More Operations --> Mapped

Then you can sweep across the plate. Attached my solution, if you have version 5.0.

Hi, Lasse

Thanks for answering the question. I am using 4.3b. So I cannot open your solution. I am kind of confuse about your operation. I need to mesh the upper plane with trianglular elements and mapped mesh at same time or you mean I either use triangluar element or mapped mesh to mesh the upper plane. I am able to mesh the upper plane (except PML layer) with free triangular and successfully sweep across the entire plane. However, the result looks not right. see attached vibration out-of-plane displacement field. Any ideas about it.

I looked at your model. I used triangular elements in the center parts where you had them. On the boundary domains I used mapped mesh which makes tetragonal elements. Then I swept them simultaneously. At least in 5.0 it works with no problems. Look at the attached image.
