Level Set Interface Density Interpolation Method#

Level Set Interface Density Interpolation Method = {char_string}

Description / Usage#

This specifies the interpolation method of the level set properties for Density

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 Density Interpolation Method = LOG

Technical Discussion#

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