sunfluidh:level_set_method_namelist

## Namelist "Level_Set_Method"

This data setup is devoted to the level set method used for the simulation of immiscible two-fluid flows.
It is not available for the release SUNFLUIDH_EDU.

## Full data set of the namelist

&Level_Set_Method Level_Set_Enabled= .true. ,
Automatic_Interface_Thickness_Scale= .false.,
Interface_Thickness_Scale= 1.175D-02 /

• This method is only used in the context of incompressible two-fluid flows at present.
• The data “Incomp_MultiFluids” must be set to “.true.” in the namelist “Fluid_Properties” for using the level set method.
• Not available for the release SUNFLUIDH_EDU .

## Definition of the data set

### Level_Set_Method Level_Set_Enabled

• Type: boolean value
• The level set method is enabled (.true.) or not (.false.)
• Default value = .false.

### Automatic_Interface_Thickness_Scale

• Type: boolean value
• The interface thickness is automatically estimated from the cell size (.true.).
• Default value = .false.

### Interface_Thickness_Scale

• type = real value
• Value of the half-thickness of the numerical interface considered between the fluids. It is only imposed when the data Automatic_Interface_Thickness_Scale= .false.
• Default value = .false.
