non-manifold edges hfss

Hi,
I've a problem in HFSS.
When I run the validate process the message viewer returns this error message:Non-manifold vertices found for part "layer" where "layer" is a part of the model.
The model is a transceiver on FR4 made from a 4 layer structure and the "layer" part is in the middle between the others.
What does this error means?
Thanks in adv.

sorry, cannot catch your word.

HFSS is complaining that the geometry "layer" you draw is not valid. Try different ways of drawing.

The error message indicates there is a problem with the mesh. This could happen if you imported the geometry from a CAD tool. You may need to re-draw that part of the model. See the link below for more info:

You can plot orther geometry instea of "layer",such as model.

I have he same problem; an error message says "no manifold vertices found".
I don't thing that there is another way to draw my model.
Could anyone help me?

Thank you.

Actually, I'm not sure whether I'm right.

But I was told that; if you're confident that you've drawn your structure in correctly, and you still get the above-mentioned error message. You can high-light the troublesome objects and do the HFSS option called "Heal Objects".

Try it! It might work, you'll never know! By the way, I think the message sometimes pop up when you have 2D objects sharing a common edge, or a loop within a loop. Hope these help.

BR,
Dave

Hi!
Thanks a lot for your help.
I have a new problem now. I did the validation check and all was right, so I started the analysis, but during the initial mesh operation the simulation stops and a new error message appears: "Initial mesh, process mesh3D: error while opening or writing the mesh files".

Please, help me again!
