Level Set Interface Viscosity Interpolation Method#
Level Set Interface Viscosity Interpolation Method = {char_string}
Description / Usage#
This specifies the interpolation method of the level set properties for Viscosity
Possible choiches for char_string:
- LINEAR
Default linear interpolation \(p = (1-H(\phi)) p_- + H(\phi) p_+\)
- LOG
Log interpolation \(p = p_-^{(1-H(\phi))} p_+^{H(\phi)}\)
Examples#
The following is a usage example for this card:
Level Set Interface Viscosity Interpolation Method = LOG
Technical Discussion#
The log interpolation has been found to behave better in some cases where material property differences are large.
