Layer Stack in Circuit

[georgmichel]

Hi,

I try to add a layer stack to a Circuit design in order to have distributed elements. I do this with:

aedtapp = Circuit()
layers = ansys.aedt.core.modules.layer_stackup.Layers(aedtapp)
layers.add_layer(
    "Top",
    thickness="35um",
    material="copper")

Then I get the error: 'circuit' object has no attribute 'model_units' on add_layer

How can I do better? Thanks.

Hi @georgmichel ,

Circuit API in PyAEDT is not yet the stackup creation.

You can of course creating it in HFSS 3DLayout which is directly connected to Circuit.

from ansys.aedt.core import Hfss3dLayout
h3d = Hfss3dLayout(version="2025.2")
h3d.modeler.layers.add_layer("TOP")
h3d.modeler.create_rectangle("TOP", [20, 20], [50, 50], name="rect_1")
h3d.modeler.create_line("TOP", [[25, 25], [40, 40]])

If you are interested in Filter, you can use FilterSolutions API:
