BUG: cyclicACMI: make conservative and remove faceAreas0
Need to review cyclicACMI patch non-overlap values
- values here preserve initial values only
- snGrad - used?
- wall functions - no longer call updateCoeffs with ACMI weights (?)
See merge request !46
- cyclicACMIFvPatchField::updateCoeffs() now again redirects to
fvPatchField::updateCoeffs(const scalarField& weights);
- which redirects to fvPatchField::updateCoeffs();
- except on wall functions where the weights are used to switch off
turbulence generation
- renamed the updateCoeffs on the fixedFluxPressure bc to updateSnGrad.
e.g. (fvc::interpolate(HbyA) & mesh.Sf()) -> fvc::flux(HbyA)
This removes the need to create an intermediate face-vector field when
computing fluxes which is more efficient, reduces the peak storage and
improved cache coherency in addition to providing a simpler and cleaner
API.
dotInterpolate interpolates the field and "dots" the resulting
face-values with the vector field provided which removes the need to
create a temporary field for the interpolate. This reduces the peak
storage of OpenFOAM caused by the divergence of the gradient of vector
fields, improves memory management and under some conditions decreases
run-time.
This development is based on a patch contributed by Paul Edwards, Intel.
//- Disallow default shallow-copy assignment
//
// Assignment of UList<T> may need to be either shallow (copy pointer)
// or deep (copy elements) depending on context or the particular type
// of list derived from UList and it is confusing and prone to error
// for the default assignment to be either. The solution is to
// disallow default assignment and provide separate 'shallowCopy' and
// 'deepCopy' member functions.
void operator=(const UList<T>&) = delete;
//- Copy the pointer held by the given UList.
inline void shallowCopy(const UList<T>&);
//- Copy elements of the given UList.
void deepCopy(const UList<T>&);
This new approach to 0 initialization is simpler, cleaner, more readable
and more efficient. The rest of the OpenFOAM code will be updated in
due course.
Wall-velocity condition to be used in conjunction with the single rotating
frame (SRF) model (see: FOAM::SRFModel)
The condition applies the appropriate rotation transformation in time and
space to determine the local SRF velocity of the wall.
\f[
U_p = - U_{p,srf}
\f]
where
\vartable
U_p = patch velocity [m/s]
U_{p,srf} = SRF velocity
\endvartable
The normal component of \f$ U_p \f$ is removed to ensure 0 wall-flux even
if the wall patch faces are irregular.
\heading Patch usage
Example of the boundary condition specification:
\verbatim
myPatch
{
type SRFWallVelocity;
value uniform (0 0 0); // Initial value
}
\endverbatim
