GunnsDraw Ground Node - nasa/gunns GitHub Wiki

Background

This represents the Ground node of a GUNNS network. In the exported network code, the Ground is a special node that always represents zero potential: pressure, temperature, voltage depending on the network aspect. There is always exactly one Ground node in the exported network code, regardless of how many Ground node shapes are in the drawing — all those shapes reference the same Ground node in the code.

Many GUNNS link types have a special relationship to the Ground node, like requiring certain ports to always connect, or never connect, to Ground. These will be detailed in the help pages for those links.

How To Use In GunnsDraw

Rules

  • You can place any number of Ground node shapes in the Network container.
  • Any number of Link Port connections can connect to a Ground node shape, or you can have one link per Ground shape. It’s up to you.
  • You can leave a Ground shape unconnected to anything. In this case, the netexport.py script will quietly ignore it.
  • We don’t intend for you to name the shape, but you can if you want. The netexport.py script will ignore any name you give it.
