Fill and Pack simulations support materials with
pressure-dependent viscosity.
Materials that have pressure-dependent
viscosity are listed in the Plastics Materials Database with an information icon 
.
Accounting for pressure-dependent viscosity is
important for parts that contain long flow lengths or very thin walls, or for cases
where you need
high injection
pressures.

Domains).
