Multiphase: Update all solvers to accommodate the split between twoPhaseMixture and incompressibleTwoPhaseMixture

interPhaseChangeFoam: No need to check continuity error and the velocity divergence defines the compressibility effect

for gasThermoType based on type of energy solved

Modified chtMultiRegionFoam and chtMultiRegionSimpleFoam to work with
anisotropic heat transfer conductivity

Update biconic25-55Run35 tutorial with simplified collapseDict

Note that smoluchowskiJumpTFvPatchScalarField still uses the specified Pr from the
thermophysicalProperties whereas it should derive appropriate information from
the thermo package

compressibleTwoPhaseEulerFoam: Improved handling of compressibility effect on continuity and boundedness
