Create: Data Sampling¶
The Data Sampling tools extract targeted simulation data from specific regions of the fluid domain. Each tool has a pre-set dimensionality which informs the structure and dimensionality of the returned sample data. For example, zero-dimensional probes return data at specific points, one-dimensional sampling lines return data along a pre-set line segment, and two-dimensional output planes return data over a pre-set sampling surface. These tools let users record targeted output which supports both quick diagnostics and detailed analysis while keeping storage overhead to a minimum.
Data Sampling tools are classified into two types: Simple and Complex. Simple tools are fully self-contained and do not require additional child geometry to operate. They perform sampling directly on the defined shape, such as a point, line, or plane. Complex tools, by contrast, rely on instructions to compute a surface or secondary geometry at runtime. Depending on the tool, this output may be based on predefined child geometry or dynamically generated surfaces derived from the simulation field.
Simple Tools
Point Probe: Probes record time-varying values at a single point. These are useful for monitoring velocity, pressure, temperature, or species concentration at key locations. Probes can be fixed in space, follow the fluid, or move along a user-defined path through the domain.
Output Line: Output lines extract continuous profiles along straight-line segments. These are useful for sampling cross sections and examining axial/radial variations in flow.
Output Plane: Output planes capture full 2D slices through the domain. These are useful for spatial visualization and analysis of transient or steady-state behavior without storing full volumetric data.
Complex Tools
Output Surface: Output surfaces allow sampling over arbitrary shapes — planar or curved — for more specialized interrogation of the flow field.
Isosurface: Isosurfaces automatically detect and record the location of a variable at a specified threshold, supporting analysis of evolving boundaries such as concentration fronts, thermal layers, or yield-stress caverns.
