If the number of segments are too many you could manually renumber them by using "select mesh element" (one of the blue icons near the top middle in CADFEKO)
Then save the model. Just remember that if you remesh the old mesh that you changed manually will be overwritten.
Else you could create...
cadfeko
Definitely use CADFEKO! EDITFEKO is for advanced settings and you only use it when it's needed. Even if you would need it, you wouldn't need it for creating any geometry. It is usually if you want to switch on/off multiple sources in one run where you could use IF statements and FOR...
transformer simulator
Wouldn't a simple circuit simulator work for you? I.e. Vipec is a free circuit simulator.
Otherwise in FEKO you can draw a few polygons and use variables in the polygon definition i.e. width, or length, etc to play around (use the optimiser) with the dimensions. The...
help in edit feko..
You only need EDITFEKO if you need to make advanced changes/settings to the model. For example in EDITFEKO you can use for loops and if statements to e.g. frequency dependent loads. You can build the geometry in EDITFEKO if you want, but it really isn't necessary!
Re: Feko help
Rays are only visible for UTD solutions. The PO is more like shining a torch on something and checking if it is visible. Rays can't be viewed for PO solutions.
For the UTD you have to make unmeshed plates and they have to be a minimum of 3 wavelengths long, otherwise the...
simlation observations
1) If you have sampled near fields they must be sampled a minimum distance of 1 triangle edge length away from the triangles.
2) This is normal. Fields will bounce around inside. If you have an outside field coming from only 1 direction then already this is not a...
If you want a specific value for the current you can use a voltage source and scale the power using the power settings in CADFEKO. So define a wire port with voltage source then run FEKO. Check the current in the source given in the OUT file. Then change the power output and run again.
You can try to define a small section of air dielectric with the current source inside of that. Remember to enable volume meshing in the create mesh dialog to activate the FEM/MOM.
(Were you looking to force a specific current? Why are the voltage sources not suitable?)
Re: Feko Help
The 80dB is my personal experience. Maybe I made some modelling mistake, dunno. As for the oblique incidence thing, I wouldn't believe everything I read :D
But seriously, I wouldn't believe a statement that just says:"FEKO does not work for oblique incidence". It depends on the...
Re: Feko Help
I doubt if the literature model was a fully enclosed one. Perhaps one with holes? If you have holes, then using the Surface Equivalence Principle you can model the inside of the enclosure with an air dielectric (eps_r=1). This will give you "dynamic range" up to about 80 dB.
Feko Help
What levels of shielding do you expect? If you have a "fully enclosed" enclosure (i.e. no holes) then the MoM can only give you about 40 dB of shielding. This is a fomulation based restriction - remember, you are discretising the currents so it can not give you infinite shielding.
If...
