Level Set Interface Momentum Source Interpolation Method#

Level Set Interface Momentum Source Interpolation Method = {char_string}

Description / Usage#

This specifies the interpolation method of the level set properties for Momentum Source

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 Momentum Source Interpolation Method = LOG

Technical Discussion#

The log interpolation has been found to behave better in some cases where material property differences are large.
