Tracer transport

diffusion

Type: positive number. Units: m²/s. Tracer diffusion coefficient.

tracerTime

Type: positive number. Units: seconds. End time for tracer transport.

tracerWrite

Type: positive number. Units: seconds. Interval between written tracer results.

tracerStep

Type: positive number. Units: seconds. Numerical time step for tracer transport.

Tracer simulation requires an existing OpenFOAM/flowStokes case. Run -t all, -t flow_tracer, or first create the flow result before using -t tracer.
