Fluid Aspect Course 4.6: Special Objects & Capabilities

Some fluid links and capabilities require more complicated set-up in GunnsDraw to use:

Sockets & Jumpers

  • In the fluid aspect, jumpers model flexible hoses that can be moved from one connection to another during run-time.
    • Most links allow you to manually change their node connections in run-time.
    • What makes jumpers special is that they can only connect to sockets, and they have a more formal user interface for connecting to & from sockets.
  • See the link help pages for GunnsFluidJumper and GunnsFluidSocket for a guide on setting them up and using them.
  • Use sockets & jumpers when you have a hose (jumper) that the user regularly needs to move around between different connection locations (sockets).
    • For hoses that always attach between the 2 same points but have a quick-disconnect to connect or disconnect them, use the GunnsFluidSimpleQd link instead.

Chemical Reactions & Compounds

Some links that can model chemical reactions, like GunnsFluidReactor and GunnsFluidAdsorber, require special set-up in GunnsDraw. See their link help pages for more info.

Trace Compounds

Trace compounds are chemical compounds entrained in the bulk fluid in low enough concentrations that we can ignore their negligible contributions to the bulk fluid properties. This allows us to model their concentrations and flow around the fluid network without the extra overhead of modeling all their fluid properties, like we do with the main fluid types.

See Trace_Compounds for more info on how to use it.

Significant limitations still apply — see Trace Compounds: Present & Future Capabilities for more info.
