Hello, I am a physics undergraduate student using FastCap2 for my project works. I am having problems on how to find the capacitance between 2 square capacitor of 10 cm and a distance of 1 mm separating them. The permissivity being #949;_0. Can somebody please help?

Hi Zoubayr,
FastCap/FasterCap do not support D elements with different permittivities on the two sides, i.e. infinitely thin conductors in contact with different materials.
FastCap/FasterCap always assume that the conductors are 3D. So you must use a conductor with thickness, that is a box, however thin, composed by panels each of which can be in contact with a different material (e.g. top different from bottom).
You can find some examples in the 'Samples' directory when you install the FastFieldSolvers bundle on Windows. For the location of the directory, if not found, you can see the embedded online help of FasterCap.
Best Regards
Enrico

Dear Enrico,
Could you please help me? I really need to know how to add the values of the permittivities in my algorithm.

It really depends on what your specific needs are. As I suggested, please contact me on my email
s u pp or t <at> fastfieldsolvers <dot> com (remove the anti-spam spaces and replace <at> and <dot> with the proper symbols)
and we can discuss your requirements.
Best Regards,
Enrico

Hi Zoubayr,
we usually perform this kind of activities as consulting services.
Kindly let me know if you are interested and in case you can contact me via email (via contact form or direct email you can find on the contacts page). We can then discuss your specific requirements so that I can provide you a quotation for you.
Best Regards,

Hi Muhammad,
I think I already answered this question; you can of course generate the models any way you like (e.g. script, by hand, via FreeCAD, etc.) and you can even modify the solvers to your liking as they are all open source.
You can pull them from Github, see the link in the download page.
Best Regards,
Enrico

Dear Enrico,
Can I write my own algorithm and generate the model without using the algorithm already provided? When I tried to do so, I was unable to generate a model.

Happy to hear that!

Dear Enrico,
I am quoting from
From capac2.lst
*
* capacitor example
*
* this parallel plates capacitor is embedded in a non-homogeneous dielectric
*
* REMARK: you have to generate the plates and dielectric geometry, before being
* able to lauch FastCap, using the cubegen_ command with the options specified
* in the comments here below.
*
* Enrico Di Lorenzo, w*w.fastfieldsolvers.com, 2002/03/29
*
* conductor to air interfaces
*
* conductor generated with
* cubegen_ -xo-0.5 -xh1 -yh0.3 -zh1 -nx20 -ny3 -nz20 -naplate -t -b -pfl -pfr -pbr > plate.qui
* note that now the dielectric constant of the medium surrounding the first conductor is 3.0
C plate.qui 3.0 0.0 0.0 0.0
C plate.qui 1.0 0.0 0.1 0.0
* dielectric to air interfaces
*
* dielectric interface generated with
* cubegen_ -xo-0.5 -xh1 -yh0.03 -zh1 -nx20 -ny3 -nz20 -nadiel -pbl > diel.qui
* note that the coordinates (0.0, 0.015, 0.5) identify a reference point
* inside the dielectric region of constant 3.0; see the FastCap manual
* for further details
D diel.qui 1.0 3.0 0.0 0.0 0.0 0.0 0.015 0.5 -
What does this means: "cubegen_ -xo-0.5 -xh1 -yh0.3 -zh1 -nx20 -ny3 -nz20 -naplate -t -b -pfl -pfr -pbr > plate.qui ?"

Dear Enrico,
It is me Zoubayr. I have lost my password, so I had to create another account. I have been unable to use the app FastModel. When I open it, a pop up appears saying: "unable to run on windows". I have tried to uninstall the app and re-install it, but the same thing is happening. I am having difficulty to proceed in my dissertation works. Could you please help me?
Regards,
Zoubayr |
