Number of correction passes in this solver-specific algorithm block.

Validation {.} >= 1

Select optimized, debug, or profiling compiler rules.

Select the compiler family used to build OpenFOAM. Availability depends on the host platform.

Select whether OpenFOAM uses system tools or compilers from its ThirdParty configuration.

Select the bit width used for OpenFOAM integer labels, such as cell and face indices.

Select the MPI implementation used when compiling parallel OpenFOAM applications.

Enable or disable OpenMP compiler and linker flags.

Select double, single, or mixed scalar precision for the compiled OpenFOAM libraries and applications.

Select the target architecture width where supported by the host compiler and operating system.

Time-step value used by the native solver. Stability and physical meaning remain solver-specific.

Validation {.} > 0

End value of the solver's native time coordinate; for steady solvers this can represent iteration time.

Validation {.} > {?control.start_time}

Select whether the case starts from its configured start time or the latest written time.

Starting value of the solver's native time coordinate. The solver determines its physical interpretation.

Select the condition that stops the solver.

Native write scheduling mode used by the selected tutorial.

Output interval; its meaning is selected by write_control (steps or solver-time units).

Validation {.} > 0

Default interpolation scheme from cell centers to faces.

Default Laplacian scheme, including its surface-normal gradient treatment.

Default surface-normal gradient scheme.
