Summary

0000360: incompressible RAS wall function "nu" at patch access error

Description

Accessing boundary nu values references deallocated memory in 12 locations throughout the incompressible/RAS/derivedFvPatchFields/wallFunctions/nutWallFunctions subfolders.

The line of concern is:
const scalarField& nuw = rasModel.nu()().boundaryField()[patchI];

I believe this line should be replaced with the following lines to avoid accessing the boundary field of the temporary volScalarField after its memory has been freed:
const tmp<volScalarField> tnu = rasModel.nu();
const volScalarField& nu = tnu();
const scalarField& nuw = nu.boundaryField()[patchI];

I apologise if this error has already been fixed or raised or if my understanding of the error is flawed.

Steps To Reproduce

Use command "grep -r "rasModel[.]nu()()[.]boundaryField()\[patchI\].*" *" to find the erroneous lines.
