3.7. Units & Expressions#
Variables in Flow360 can represent solver inputs (e.g., time step, flow speed), intermediate parameters (for relationships between quantities), or derived quantities for post-processing.
Units define the dimensional context for these quantities. Flow360 automatically checks dimensional compatibility, preventing invalid combinations (like adding pressure and temperature).
Both variables and units can be managed through the WebUI or Python API, and Flow360 supports fully unit-aware symbolic expressions.
Note
All Flow360 mathematical expressions are unit-aware, meaning any operation involving mismatched dimensions will raise an error.
