Polymer Shock Capturing#

Polymer Shock Capturing = {NONE | DCDD <float1>}

Description / Usage#

This optional card is used to specify the shock function for the polymer stress equation. Valid options are

NONE: No polymer shock capturing is used, default
DCDD: DCDD shock capturing term is used (currently only in LOG_CONF/LOG_CONF_GRADV) * <float1> the scaling value of the shock capturing term
YZBETA: YZBETA shock capturing term is used (currently only in SQRT_CONF) * <float1> the scaling value of the shock capturing term

Currently only available for log-conformation / sqrt-conformation formulations.

The following is a sample card that set the polymer shock function to SUPG and demonstrates the required cards.

Polymer Shock Capturing = DCDD 1.0

The following is a sample card that set the polymer shock function to NONE.

Polymer Shock Capturing = NONE
