What a SysML internal block diagram is.
A SysML internal block diagram shows the parts inside one system block and the connections between them. It is the view for a battery pack, instrument, vehicle subsystem or spacecraft when you need to explain what is inside and how the parts interact.
Use the parts as the nouns in the system and label the connections with the energy, material, data or command that passes between them. Keep a context diagram for outside actors; use this diagram to expose the structure within the system boundary.

Who uses SysML internal block diagrams.
Subsystem boundaries and interfaces for a design review, from sensors through controllers to actuators.
The major parts, power paths and feedback loops inside equipment before detailed electrical design.
Controllers, sensor feedback, pumps and valves arranged as a clear irrigation-system structure.

Common questions
What is a SysML internal block diagram?
A SysML internal block diagram, or IBD, shows the internal structure of a block: its parts, ports and connectors. It is used to model the components of a system and the interactions between them.
What should I include in a SysML internal block diagram?
Include the parts inside the system, their important interfaces, and the material, energy, data or control flows between them. Add nested components only when they clarify the design.
How do ports work in a SysML internal block diagram?
Ports are interaction points on a part or system boundary. They define where a part provides or receives an interface, such as power, a sensor reading or a command.
What is the difference between an internal block diagram and a context diagram?
An internal block diagram explains what is inside a system. A context diagram keeps the system as one block and focuses on people, neighboring systems and other external actors.
