boundaryRadiationProperties: updating to new format
dynamicMeshDict and snappyHexMeshDict in utorials/multiphase/interDyMFoam/RAS/motorBike to follow Mattijs Git lab id 381
- Introduce writeList(Ostream&, label) method in various List classes to
provide more flexibility and avoid hard-coded limits when deciding if a
list is too long and should be broken up into multiple lines (ASCII only).
- The old hard-code limit (10) is retained in the operator<< versions
- This functionality is wrapped in the FlatOutput output adapter class
and directly accessible via the 'flatOutput()' function.
Eg,
#include "ListOps.H"
Info<< "methods: " << flatOutput(myLongList) << endl;
// OR
Info<< "methods: ";
myLongList.writeList(os) << endl;
Now the interFoam and compressibleInterFoam families of solvers use the same
alphaEqn formulation and supporting all of the MULES options without
code-duplication.
The semi-implicit MULES support allows running with significantly larger
time-steps but this does reduce the interface sharpness.
- templated code that is not actually be used yet.
ENH: avoid combineFields for serial case
Note: a 'master-only' variant with combineList only on the master and
without scatter can be pursued later.
Description
Simple solidification porosity model
This is a simple approximation to solidification where the solid phase
is represented as a porous blockage with the drag-coefficient evaluated from
\f[
S = - \alpha \rho D(T) U
\f]
where
\vartable
\alpha | Optional phase-fraction of solidifying phase
D(T) | User-defined drag-coefficient as function of temperature
\endvartable
Note that the latent heat of solidification is not included and the
temperature is unchanged by the modelled change of phase.
Example of the solidification model specification:
\verbatim
type solidification;
solidificationCoeffs
{
// Solidify between 330K and 330.5K
D table
(
(330.0 10000) // Solid below 330K
(330.5 0) // Liquid above 330.5K
);
// Optional phase-fraction of solidifying phase
alpha alpha.liquid;
// Solidification porosity is isotropic
// use the global coordinate system
coordinateSystem
{
type cartesian;
origin (0 0 0);
coordinateRotation
{
type axesRotation;
e1 (1 0 0);
e2 (0 1 0);
}
}
}
\endverbatim

if convergence is not achieved within the maximum number of iterations.
Sometimes, particularly running in parallel, PBiCG fails to converge or diverges
without warning or obvious cause leaving a solution field containing significant
errors which can cause divergence of the application. PBiCGStab is more robust
and does not suffer from the problems encountered with PBiCG.
- Constructs a validated word, in which all invalid characters have
been stripped out and any leading digit is '_'-prefixed.
Words with leading digits cause parse issues when read back later.
- Replaces previous functionally identical code from src/conversion
--
COMP: test against nullObject instead of checking address for null pointer.
- The code create a box with a (0,0,0) point.
The new definition is more logical and makes it very easy to grow
the bounding box to include new points. It also simplifies much of
the logic in the constructors.
- Use ROOTVGREAT instead of VGREAT for sizing greatBox and invertedBox.
Avoids some overflow issues reported by Mattijs (thus GREAT has been
used in treeBoundBox), but might still need further revision.
- Constructor for bounding box of a single point.
- add(boundBox), add(point) ...
-> Extend box to enclose the second box or point(s).
Eg,
bb.add(pt);
vs.
bb.min() = Foam::min(bb.min(), pt);
bb.max() = Foam::max(bb.max(), pt);
Also works with other bounding boxes.
Eg,
bb.add(bb2);
// OR
bb += bb2;
vs.
bb.min() = Foam::min(bb.min(), bb2.min());
bb.max() = Foam::max(bb.max(), bb2.max());
'+=' operator allows the reduction to be used in parallel
gather/scatter operations.
A global '+' operator is not currently needed.
Note: may be useful in the future to have a 'clear()' method
that resets to a zero-sized (inverted) box.
STYLE: make many bounding box constructors explicit
reduce()
- parallel reduction of min/max values.
Reduces coding for the callers.
Eg,
bb.reduce();
instead of the previous method:
reduce(bb.min(), minOp<point>());
reduce(bb.max(), maxOp<point>());
STYLE:
- use initializer list for creating static content
- use point::min/point::max when defining standard boxes
