The Clang compiler does not use std::move to transfer the result of the ternary
operator into the phase-fraction field resulting in it not being registered to
the database. To work around this limitation/bug the ternary operator is now
provided with tmp fields the result of which is passed with an IOobject to the
final field constructor to ensure it is registered and the IO options set
correctly.
An enumeration has been added to the arguments of the allocation
coefficient function, eta, to allow specification of how to allocate out
of bounds of the population balance size-groups. There are two options:
- "Clamp" will create an out-of-bounds allocation coefficient of exactly
one. This partitions unity across all size-space.
- "Extrapolate" will create an out-of-bounds allocation coefficient in
proportion to the ratio between the given size and the nearest
size-group size. This does not partition unity outside the range of
the size-groups.
The previous operation is equivalent to "Extrapolate".
It is not yet clear which method is preferable and under what
circumstances. More testing is required. The enumeration has been
created to facilitate this testing.
Currently in compressibleVoF vDot contains only the compressibility dilatation
effect whereas in multiphaseEuler the effect of sources are also included but
this will be refactored shortly so that the handling of mass sources and
compressibility is consistent between VoF and Euler-Euler solvers.
The previously hard-coded 1e-4 division stabilisation used when linearising vDot
for bounded semi-implicit solution of the phase-fractions is now an optional
user-input with keyword vDotResidualAlpha, e.g. in multiphaseEuler:
solvers
{
"alpha.*"
{
nAlphaCorr 1;
nAlphaSubCycles 2;
vDotResidualAlpha 1e-6;
}

IsothermalSolidPhaseModel does not update energy and density from pressure
whereas IsothermalPhaseModel does to allow compressible fluid phases to change
volume due to pressure changes.
for thermophysical transport within stationary solid phases. This provides a
consistent interface to heat transport within solids for single and now
multiphase solvers so that for example the wallHeatFlux functionObject can now
be used with multiphaseEuler, see tutorials/multiphaseEuler/boilingBed.
Also this development supports anisotropic thermal conductivity within the
stationary solid regions which was not possible previously.
The tutorials/multiphaseEuler/bed and tutorials/multiphaseEuler/boilingBed
tutorial cases have been updated for phaseSolidThermophysicalTransportModel by
changing the thermo type in physicalProperties.solid to heSolidThermo. This
change will need to be made to all multiphaseEuler cases involving stationary
phases.
This change makes multiphaseEuler more consistent with other modules and
makes its sub-libraries less inter-dependent. Some left-over references
to multiphaseEulerFoam have also been removed.
