## 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.

## non-manifold vertices found for part

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

## hfss error messages

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.

## hfss non manifold edges

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

## non-manifold edge hfss

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!
