I've been trying to create a set of super blocks using Electrical blocks & even with a very simple circuit, Xcos throws the error "The number of equations doesn't match the number of variables".

My circuit consists of a 3 phase supply connected to a 3 phase load. In the form below, it works just fine. No errors whatsoever. Note that I haven't even added the scope blocks yet. No error diagram

However, the moment I move those resistors to a superblock, Error diagram

I start getting the following error - Error msg

Here's the link to the Zcos file

Could someone please throw some light on what's going on here?

  • I downloaded Scilab and loaded your example. I couldn't get the error you had indicated but got other ones. The issue for me was I could never actually get to the code of the model to trouble shoot. Highly recommend trying to reproduce your model in OpenModelica so you can look at the code directly. – Scott G Mar 20 '18 at 13:09
  • Which version of Scilab did you use? I tried it on 2 different PCs with both 5.5.2 & 6.0.1 (the latest) and got the exact same error. – Sunny Yates Mar 20 '18 at 14:15
  • 6.0.1 on windows. The file you linked when opened wouldn't simulate at all. Just gave some sort of cryptic "Invalid" error on the console screen. I deleted the top resistor and put it back. The thing seemed to simulate but there were never any results and the error you had didn't show up. Very confusing. – Scott G Mar 20 '18 at 14:25
  • I didn't add any scope blocks to keep things simple, so you won't get any results. That was expected. Could you load your file somewhere & share a link to it? Also, when you said you deleted the top resistor, did you do this inside the superblock? – Sunny Yates Mar 20 '18 at 15:23
  • http://dropcanvas.com/nrnuh - I put the original (orig) and modified (mod) files at that link. No I deleted and re-added the top resistor (the component between the voltage source and superblock). – Scott G Mar 20 '18 at 15:31
