Hello everyone, I have the following problem when running my model, these problem are shown below, Does anyone know How can I correct these errors? Thanks.

In order to discard the third element of the input bus, you need a third output on the demux, which you can connect to ground.

Thank you sir, but this error came from the diode block that I add from the library.

[Walter Roberson]

Then throw in another step that breaks up the bus or vector of length 3 to only have the two components needed by the library block

@walter Riberson, Good day Sir, can you answer me this question? Why I can't connect one library to another library? Even the connection port can't connect anywhere in the model/output. Is there's another way to connect two modesl/library?

Step by Step process would be a big help for me. Thank you

When you cannot connect one library to another library, then often the reason is that the two libraries belong to different problem domains. For example one of the libraries might have to do with fluid simulation and the other might have to do with electrical work.

The Specialized Power Systems parts of SimScape Electrical is considered a different problem domain than the rest of SimScape Electical if I remember correctly, and SPS is considered a different problem domain than basic MATLAB. There ends up being up to three different ways of representing some of the common object such as capacitors or power sources, and those ways will not normally talk to each other.

There are connector blocks that can convert some kinds of signals between problem domains, but in my experience more often this kind of problem is telling you that you need to read carefully through the list of blocks to find a different representation of what you are trying to do, so that you do not cross between domains.

Good Morning Sir, Can I asked your opinion about my model? I have created an induction motor with a Variable frequency drive, and I want to connect it to a single-phase inverter that have an output of 230V. I don't know what to do sir since the output is not correct when I connected the inverter to induction motor, I hope you can help me and give me some suggestions. Thanks in advance sir.
