Default viscosity model

Calculates a mathematical viscosity model, which is required to simulate material viscosity properties accurately during a flow simulation.

Matrix, Cross-WLF, and Second Order are the viscosity models used for thermoplastics. For materials in the Autodesk Moldflow database, the appropriate default viscosity model is selected.

To view the viscosity model, click View viscosity model coefficients and display the coefficients.

To specify the default viscosity model, select the model from the drop-down list.
