Indeed, I’m currently thinking about the date for a new release. But I don’t know if it will come this year.
Yes, you are right! That’s not as it should be. Thanks a lot for reporting it. It will be fixed in the coming release.
It came from the lowpass filter design, but for bandpass filters it’s indeed unnecessary.
Hello,
the uSimmics/QucsStudio license complies indeed as you wrote, i.e. you are allowed to use the program freely within your company, but any commercial redistribution, modification or implementation into other non-free products are forbidden. I have updated the legal site to clarify this.
If you have further questions or remarks of any kind, please let me know. And if you like the program, please consider to make a donation.
Hello,
many thanks for the bug report! I can reproduce it. I happens because inside the subcircuit (BAR64), the port nodes are labeled. Thus, the best work-around is to delete these labels. I will fix it in the next release.
Thanks for the praise! I’m glad that you like it.
The unit “mil” can be used after numbers like all other units, too. So, “10 mil” works, but “var1 mil” does not. Usually, I recommend to define a variable with unit, e.g. “var1=10 mil”, and not separate the number from the unit.
Indeed, there are no global variables in uSimmics. The usual way is to define subcircuit parameters instead. Please read the section “Working with Subcircuits” in the program help (F1 key) to see how this is done.
Concerning optimizations, yes, it is performed if (and only if) an optimization component is placed into the schematic. This can be disabled if it should not be used anymore. (right-click on it and choose “Deactivate/Activate”)
Good luck!
Hello Larry,
>>1st paragraph, sentence after “(7)”. “You will be ask…”. “ask” should be “asked”.
You’re right, thanks for reporting it! I will fix it.>>2nd paragraph, 3rd line, “Pressing the right mouse button … doesn’t work for me
That’s strange. I tested it on several machines from WinXP to Win12 without problems. If your right-mouse button works in other applications, I won’t have an explanation for this behavior.>>The ground symbol you have is for an “earth ground”…. (Reference IEC 60617 or IEEE 315, clause 3.9.1)
This reference also states that the “earth ground” symbol is used for “general ground”, too, so I think it’s correct here.>>Units of measure are considered common nouns and are not capitalized. “50 Ohm”….
You’re right again. I will use the capital omega instead.Hm, maybe a nice feature. I will think about it. Currently, I don’t know how the user could enter all necessary infos in a adequate way. But let’s see…
Currently, the EM simulation calculates the first row of s-parameter matrix only, because each row would mean a new, time-consuming simulation (due to FDTD). Therefore, a conversion into sNp file is not possible. Sorry for this!
Yes, this is intentional. stoz() does the same job, so please use this function. ztor() is still needed and thus, does still exist.
Very nice indeed! It’s especially noticeable that several guys ask for a video series with QucsStudio tutorials. I’ve also been thinking about something like this for some time now. But are there enough people that are interested in it?
The maker of the above-mentioned video obviously has many supporters. I really would like to know how he has managed to get them. Maybe start a tutorial series as crowd-funded project?
