Matlab circuit simulation

I am new to MATLAB and i want so simulate basic circuit, but i can't connect elements together. All i get is some red dotted line and a warning:

Unconnected output line found on 'D1/DC Voltage Source' (output port: 1)

How can i connect those elements together? Here is an image of what I am trying to achieve.

I know it's a rookie question, but i didn't find an answer using Google.

Solution

  • Matlab version: R2012a
    I find the Series RLC Branch block used under Simscape -> SimPowerSystems -> Elements,
    and the DC Voltage Source block used under Simscape -> Foundation Library -> Electrical Sources. The 2 nodes are both white rectangles.
    And there is another DC Voltage Source block under Simscape -> SimPowerSystems -> Electrical Sources. The 2 nodes are both white squares.
    There are some difference in the appearence of this two sources such as the shape of node. Maybe the function is different too.
    After i connect these blocks, the red dotted line indeed disappear.

    I think the reason is that electrical and powersystem are very different things.
    When you simulate basic circut, you should use blocks under the same branch to avoid electrical conflict.
