Description

Abortion

Opens the Abortion tab, see Abortion, for defining convergence criteria when solving buoyancy driven convection.

Multiphase

Opens the Multiphase tab, see Multiphase, for specifying the updating of the interface between the solid and the liquid phase.

Ramps

Opens the Ramps tab, see Ramps, for specifying a ramp for the density, heat capacity or viscosity. This is useful when it is not possible to obtain a solution with the real material properties.

e.g. the ramp starts with an increased viscosity and/or a decreased heat capacity and runs towards the final values.

Solver

Opens the Solver tab, see Solvers, for selecting a solver for velocity correction and for pressure correction. Usually the default values should not be changed.

Turbulence

Opens the Turbulence tab, see Turbulence, for selecting the numerical parameters used by turbulence model.

Automatic structured mesh tabs

Numerical parameters fo created domains of the structured mesh.

For more see details see section Setting convection on structured mesh parameters.
