AEDT Unable to Make a Cross Section

[marcberthoud]

I'm in AEDT and would like to have a cross section to analyze the fields and see the mesh. Web search indicates I have to select the object I'm interested in then go to ... -> Surface -> Section.. But the sections is NOT AVAILABLE. What is the simplest way to get a cross section to be able to see fields and meshing inside a cube? Screenshot is at

The easiest method is to use the Clip Plane function.
First, create the plane you want to display the cross-section on by selecting the menu Draw > Plane.
With the plane you just created selected under Planes in the Model tree, select the menu View > Clipping > Add Clip Plane.
In the Clip Plane dialog box, planes with "Enabled" checked will be enabled for cross-section display. Checking "Flip" will reverse the direction of the cross-section.

Thank you for the details. Clipping planes is useful and while I can add a clipping plane using "Specify center, normal" the "Use selection doesn't work as shown in the attached screenshot. Any recommendation? Thanks

When selecting a face using "Use selection," are you setting the Selection Mode to Face? Clip Plane does not work with Objects, etc.

Thank you, this is very useful and allows me to study the inside of the mesh. Quick followup, is there a simple way to move a cliping plane? The only way I found is to moving the non-model plane and defining a new clipping plane with it.

I also found that the mesh is much coarser than I want it to be as I'm interested in accurate model of the fields. Is there a way to limit the maximum length of any mesh edge?

Thanks

Yes, please run Clip Plane using that method.

To manually configure meshing, select the object for which you want to generate a finer mesh, and then go to the menu HFSS > Mesh > Assign Mesh Operation.

 

For dielectrics, you can set the maximum mesh length of the Initial Mesh by selecting Inside Selection > Length Based...

 

For conductors, you can set the maximum mesh length of the Initial Mesh by selecting On Selection > Length Based...

 

Note that the maximum mesh length set manually is applied during the Initial Mesh process. Further finer meshes may be generated in areas requiring higher precision during subsequent Adaptive analysis.
