PTT Xi parameter#

PTT Xi parameter = {model_name} <float>

Description / Usage#

This card is used in the Phan-Thien Tanner model in the nonlinear stress terms. The card should be included in the input when the option selected for the Polymer Constitutive Equation card is PTT. Definitions of the input parameters are as follows:


Name of the model for PTT Xi parameter.

  • <float> - the value of the PTT Xi parameter.

This card does not have to be present for constitutive equations other than PTT.


The following is a sample card that sets the PTT Xi parameter to 0.1:

PTT Xi parameter = CONSTANT 0.10
