33.21.6 Sample Trajectories Dialog Box

The Sample Trajectories dialog box allows the writing of particle states (position, velocity, diameter, temperature, and mass flow rate) at various boundaries and planes (lines in 2D). See Section  23.7.6 for details about the items below.

Controls

Boundaries   lists boundaries that can be chosen as the surfaces at which samples will be written.

Lines   (in 2D) lists lines that can be chosen as the surfaces at which samples will be written.

Planes   (in 3D) lists planes that can be chosen as the surfaces at which samples will be written.

Release From Injections   lists injections from which the injection to be tracked is chosen.

Append Files   causes the results of multiple calculations to be appended to a single file.

Accumulate Erosion/Accretion Rates   causes erosion and accretion rates to be accumulated for repeated trajectory calculations.

User-Defined Functions   allow control of the format and the information written for the sample output.

Output   contains a drop-down list of available user-defined functions.

Compute   causes the particles to be tracked and their status to be written to files when they encounter selected surfaces. This button will not appear for unsteady particle tracking.

Start   initiates sampling for unsteady particle tracking. This button will replace the Compute button if you are performing unsteady particle tracking. After you click it, it will change to the Stop button. Click Stop to stop the sampling. (The label will change back to Start.)
