This boundary condition provides a wall constraint on the turbulent viscosity (i.e. nut
) based on velocity (i.e. U
), for low- and high-Reynolds number applications.

This boundary condition provides a wall constraint on the turbulent viscosity (i.e. nut
) based on velocity (i.e. U
), for low- and high-Reynolds number applications.
As input, the user specifies a look-up table of u+
as a function of near-wall Reynolds number.
The table should be located in the $FOAM_CASE/constant
directory.
<patchName> { // Mandatory entries type nutTabulatedWallFunction; uPlusTable myUPlusTable; // Inherited entries ... }
where the entries mean:
Property | Description | Type | Reqd | Deflt |
---|---|---|---|---|
type | Type name: nutUTabulatedWallFunction | word | yes | - |
uPlusTable | u+ as a function of Re table name | word | yes | - |
The inherited entries are elaborated in:
