Define/Models/Multiphase... menu item opens the
Multiphase Model panel.
Multiphase Model Panel
Multiphase Model panel allows you to set parameters for modeling multiphase flow. See Sections
23.11.2 for details.
allows you to select one of three multiphase models.
disables the calculation of multiphase flow.
Volume of Fluid
enables the VOF model described in Section
enables the mixture model described in Section
enables the Eulerian model described in Section
enables the wet steam model described in Section
Number of Phases
allows you to specify the number of phases for the multiphase calculation. You can specify up to 20 phases.
contains parameters related to the VOF model. This section of the panel will appear only when
Volume of Fluid is the selected
allows you to select the desired interface-tracking scheme.
enables the Euler explicit scheme, described in Section
enables the implicit scheme, described in Section
enables the donor-acceptor scheme, described in
23.3.2. This option will appear only for quadrilateral and hexahedral meshes.
enables the geometric reconstruction scheme, described in Section
specifies the maximum Courant number allowed near the free surface. This item will not appear if the
VOF Scheme is
Implicit. See Section
23.10.4 for details.
Open Channel Flow
enables the model to study the effects of open channel flow. See Section
23.3.9 for details.
contains options related to the
enables/disables the calculation of slip velocities for the secondary phases as described in Section
23.4.5. See also Section
Body Force Formulation
contains an additional option for body force calculations.
Implicit Body Force
enables the implicit body force treatment described in Section
