I'm an Italian student trying to use HFSS for the first time to simulate a power divider in stripline.
I created my 3d model and I was trying to validate it but there should be some problems about it; does anybody know what this message "non manifold edges found for box1" means?
Box 1 is my stripline structure obtained joining different

Hi. I am new to HFSS and am encountering the following problem.
I am modeling two cascaded cavities and am getting the following error. 'Non-manifold edges found for ...'.
I have narrowed the problem to the point that I have removed all the walls except for a vertical plate attaching at the center of a a horizontal plate. I am still getting t

Non-manifold means that some geometries have mixed dimensions and cannot be manufactured. In your case you have a 3D object which touches itself at a point or edge, look at the picture bellow:
Your circular tubes are to close to the the middle tube.Try to expand the the thin edge

Hi, I am currently working through validating my device design and am confronted with the error message "Non-manifold edges found for part..." I understand the definition of this message and have read that to overcome this problem, I ned to ensure the components overlap so they can be united/intersected. I have a series of Aluminium components alon

I am trying to design Minkowski island based fractal patch antenna in HFSS ver 10. When I substract the Patch from the fractal the error " Non-manifold vertices found for part Patch " is displayed while validating. How can we resolve this issue. any help will be appreciated. The picture of the antenna is attached.

First of all, you are trying to use HFSS 11. ANSYS is now up to HFSS 15. I would suggest you upgrade your version as there have been many updates to the modeler over the years. Secondly, a non-manifold error occurs when some part of your object somehow intersects with another part of your object. It's a rather complicated mess to be in. I suggest y

I'm new to this board and have a little analog problem that maybe someone can help me with.
I'm trying to find a way to delay the rise in signal voltage from the Charge Air Pressure Sensor on my car. I would like to slow the signal rise down so that when my turbocharger starts to increase manifold pressure, the sensor's output is delayed and do

Go grab a book of "Differential Geometry" (just basics, not about manifold). Your question can be answered by the first one or two chapters.

In this theory of general relativity, spacetime is treated as a 4-dimensional Lorentzian manifold which is curved by the presence of mass, energy, and momentum (or stress-energy) within it. The relationship between stress-energy and the curvature of spacetime is governed by the Einstein field equations. The motion of objects being influenced solely

Do you know about manifold absolute pressure (MAP) sensor?
What type of its output waveform?
I have known it produce a voltage proportional with pressure.
What is it limit output voltage?
Can PIC microcontroller(PIC16F877) use this signal directly from sensor?
Is it need any circuit?

Not sure how you want to convet the image.
i.e by a code in MATLAB or something else. but it is possible generally.
If you want a specific way, Let me try for it.

I'm testing some fractal-shape antennae like Sierpinski triangle (and gasket) and Hilbert Curve, etc. I'm having some problems due to non-manifold edges with Sierpinski triangle. I'm working with HFSS V.10.
I followed this steps: create a triangle, copy it, scale it (0.5), rotate it 180 and substract to the bigger one. If I try to sim

The dynamical system concept is a mathematical formalization for any fixed "rule" which describes the time dependence of a point's position in its ambient space. The mathematical models used to describe the swinging of a clock pendulum, the flow of water in a pipe, or the number of fish each spring in a lake are examples of dynamical sy

I want to see how long my UFH is on for over a period of time. I do not want to
know when but just '3 hours today' or ' 35 hours this week' etc.
I was thinking of something connected in parallel with the manifold pump would
do but I cannot fined a timer suitable. I just want to accumulate time.

Here's what I'm trying to achieve.
I have 8 soft tube pipe (usually found in fish tanks) coming out from a small manifold, to an aquarium air pump. The tubes then go into an aquarium.
I'm trying to control every individual tube, how can I achieve it?
What should I add to control the air flow for every tubes?
It's either totally blocking
