Description: This input card is used with the log-conformation
tensor (with Polymer Constitutive Equation = {OLDROYDB | GIESEKUS | PTT} and
Polymer Stress Formulation = LOG_CONF in the material file). It is included with
the card "Conformation Map = {yes|no}" right after the Initial Guess
card and lets Goma know if the stress it's reading in is the regular polymer stress
or the log-conformation tensor stress. When it reads in the regular polymer
stress, you need to set "Conformation Map = yes". If the stress is already
read in as the log-conformation tensor, set "Conformation Map = no".
Example:

Initial Guess = read_exoII_file initial_guess.exoII
Conformation Map = yes
