      It’s not really true, that I don’t like the philosophy of open source projects. But I had to learn in many years that it simply doesn’t work. Anyway, I’ve battled for a long time to keep QucsStudio alive, but struggled in vain for support of the users.

      And, yes, QucsStudio will never make me rich!

        Many thanks for the report! There is indeed a bug in the calculation that always appears if the gap between the lines is greater than 20 times the metal thickness. I will fix it in the next version.

          The idea is, of course, that interested people can define by themselves what they want to see. Anyway, a starting point could be an introduction that shows how QucsStudio is intended to be used. This way, typical (maybe unknown) features are explained automatically.  After this, the users may ask questions about problems they encounter etc.

            How big is the interest in a Linux version?
            Are there a few people who are willing to donate for it?

              The error is strange, because msvcp100.dll comes with the QucsStudio package.

              Are you sure that the original ones are used? Or are there other versions installed in C:/Windows/system32 or similar? Have you told Wine to use “native and buildin libs”?

                The voltage arrow is correct. It always goes from positive to negative potential. This is the same in passive and in active components.

                Yes, maybe it’s clearer to draw + and – signs here. Perhaps I will change this.

                  Seems to be a nice feature indeed. If anyone can help here that would be great!

                  I’m still not sure about the exact background of this simulation. The quality of the above-mentioned video is so poor that I can’t read the text. Thus, a first step would be to define how the analysis works, what features are needed, how the component models are defined etc.

                  Is this a spreadsheet calculation only, or a more sophisticated one?
                  What effects can be simulated and where are the limits (large-signal noise, noise sidebands, …)?
                  Are the vendor models in the video are built with the dataheet parameters only (gain, noise figure, IP3 etc.), or with a kind of macro model?

                    The input current has the wrong polarity! It doesn’t flow into the transmission line, because the arrow at the input of the voltage-controlled current source points upwards and therefore, gets a negative voltage.

                    You can either flip the voltage source, set the voltage to -1V or the transconductance to -1S.

                      You are right! There is a bug. I will fix it in the next version.

                      Thanks for the report!

                        I tested this on three different system, but it doesn’t crash!?

                        Any idea which component causes the crash?
