Parts in these systems may interact by many different means, such as software operations, discrete state transitions, flows of inputs and outputs, or continuous interactions. Source OMG Systems Modeling Language (SysML) 1.6
SysML directional FlowProperty contracts for ProxyPorts SHOULD be satisfiable Property-wise (including as subsets of Properties) not necessarily just at the level of entire Blocks!
To signify that only water flows between the pump and the tank, we can specify an ItemFlow of type Water on the connector. Source OMG Systems Modeling Language (SysML) 1.6
For example, a pump connected to a tank: the pump has an "out" flow property of type Liquid and the tank has an "in" FlowProperty of type Liquid. Source OMG Systems Modeling Language (SysML) 1.6
A FlowProperty signifies a single flow element to/from a block. A flow property has the same notation as a Property only with a direction prefix (in | out | inout). Flow properties are listed in a compartment labeled flow properties. Source OMG Systems Modeling Language (SysML) 1.6
Conjugation is specified by a constraint giving the features of ~InterfaceBlocks according to those of their original InterfaceBlocks ... It is expected that tools conforming to this specification automatically create features of ~InterfaceBlocks. Source OMG Systems Modeling Language (SysML) 1.6
InterfaceBlock ... for example, in flow properties are conjugated as out flow properties and provided features are conjugated as required features. Source OMG Systems Modeling Language (SysML) 1.6
The ~InterfaceBlock stereotype (shall be pronounced: "conjugated interface block") is a specialization of InterfaceBlock that has the same features as its original InterfaceBlock except that its DirectedFeatures and FlowProperties are reversed (conjugated Source OMG Systems Modeling Language (SysML) 1.6

A FlowProperty signifies a single flow element to/from a block. A flow property has the same notation as a Property only with a direction prefix (in | out | inout). Flow properties are listed in a compartment labeled flow properties. Source OMG Systems Modeling Language (SysML) 1.6
FlowProperty naming. Use anonymous or just 'i' for in, 'o' for out, and 'io' (or 'oi') for inout. "Trust the Type". For conjugation ~InterfaceBlock use 'o' for in, 'i' for out, and 'io' (or 'oi') for inout.
FlowProperty::direction : FlowDirectionKind [1] Specifies if the property value is received from an external block (direction="in"), transmitted to an external Block (direction="out") or both (direction="inout"). Source OMG Systems Modeling Language (SysML) 1.6
For Blocks and Interface blocks with one or more FlowProperty items, choose a direction convention and use it across one project.
