Settings for Volume-of-Fluid solvers

For the Volume-of-Fluid (VoF)s solver cfdemSolverInter restrictions resulting from the phase boundary must be taken into account.

In general, discontinuities may arise at the fluid-fluid interface, for instance in the pressure field. These discontinuities render the results of interpolation or gradients calculated across this interface numerically very delicate and usually meaningless.

noParticlesAtInterface

Default:

false

Type:

Switch

Forces the user to confirm that particles are not close to the liquid-gas interface in case

• Pressure gradients are used due to the gradPForce forceModel being present.

• Any force model will interpolate fluid fields to the particle positions.

phaseChange

Default:

true if a temperatue field called T is defined in the startTime folder, false otherwise

Type:

Switch

Consider phase change or solve for the temperature field. Can be dectivated manually using this switch, see also cfdemSolverInter.
