Epsilon Regularization

Epsilon Regularization = CONSTANT <float>

Description / Usage

This card is used to specify the model for the regularization used in the generalized Newtonian viscosity.

Currently used for HERSCHEL_BULKLEY models

CONSTANT <float>

We set the epsilon value to the float specified

Examples

The following is a sample card that sets Papanastasiou regularization to a HERSCHEL_BULKLEY fluid with an epsilon on the power law term

Liquid Constitutive Equation = HERSCHEL_BULKLEY
...
Regularization Model         = PAPANASTASIOU_EPSILON
Epsilon Regularization       = CONSTANT 1e-12

Similarly applying only to the Yield term for epsilon regularization

Liquid Constitutive Equation = HERSCHEL_BULKLEY
...
Regularization Model         = EPSILON_YIELD_ONLY
Epsilon Regularization       = CONSTANT 1e-5
