Meanflow Conversion

Set parameters to control the HDF5 to meanflow.bin conversion step.

Key	Type	Default	Description
`i_s`	`int`	`0`	Start index
`i_e`	`int`	-	End index
`d_i`	`int`	`1`	Index stride
`set_v_zero`	`bool`	`true`	Zero out wall-normal velocity
`nondimensionalize`	`bool`	`false`	Scale dimensional flow fields by freestream references

Adjust these fields when the converted meanflow should use a specific streamwise slice range or stride.

When dimensional input is detected but this option is false, lst-tools lastrac warns that dimensional values will be written. For the legacy lst.x workflow, set it to true when nondimensional profiles are required. Velocity is scaled by uvel_inf, temperature by temp_inf, and pressure by dens_inf * uvel_inf²; ensure those freestream values match the HDF5 data. The source HDF5 is not changed.

Example

[meanflow_conversion]
i_s        = 0
i_e        = 200
d_i        = 1
set_v_zero = true
nondimensionalize = true
