Block Flow Diagram Definition. Each block can depict a single piece of equipment or a stage in a process. A block definition diagram is a static structural diagram that shows system components their contents properties behaviors constraints interfaces and relationships.
The term functional in this context is different from its use in functional programming or in mathematics where pairing functional with flow would be ambiguous. A block is a modular unit of structure in sysml that is used to define types of physical entities e g. Blocks are connected by straight lines representing process flow streams.
The figure below illustrates the vehicle structure of defined blocks in the sysml block definition diagram.
Block definition diagram bdd. It is an alternative to using a circle. A block is a modular unit of structure in sysml that is used to define types of physical entities e g. A block definition diagram is a static structural diagram that shows system components their contents properties behaviors constraints interfaces and relationships.
