AI Thread Summary
The size of the lumped RLC in HFSS significantly affects simulation results, particularly in terms of resistance and impedance matching. Users are seeking guidance on how to set the sheet size to minimize its impact on the simulation. It is noted that the component value is inherently dependent on the area specified, meaning the shape and size must reflect the physical component for accurate results. Adjusting the size of the lumped RLC will alter the simulation outcomes, making it crucial to define the dimensions appropriately. Ultimately, achieving accurate simulation results requires careful consideration of the lumped RLC's size and properties.

Hi Guys
When I use lumped RLC in HFSS, I find that its size can influence the simulation result. How do I set the sheet size of lumped RLC? Make it square is better? Thanks.

I do not use Ansys HFSS, but I would question the 2D? size of the Lumped RLC in wavelengths.

If you were using Lumped RLC to define a resistance, then size and the resultant resistance would change the termination and impedance matching.

Yes, I set lumped RLC on 2D sheet in HFSS. And when its size changes, the result changes too. So I want to know how can I set a resistor/inductor/capacitor in HFSS without the influence of sheet size.

I do not believe you can. Where the lump has properties specified per unit area, the component value will be dependent on the area. You will need to define the component shape and size as the area of the physical component to be used later in manufacture, and then give it the appropriate properties to get the value required.
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
