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.
