3.5.1 The Concept of Fiber Materials

The material properties you specify for the fibers are used for all fibers defined in your model. You cannot consider fibers consisting of different fiber materials in one simulation.

The continuous fiber model makes use of ANSYS FLUENT's material concept for the Material Type of the fluid. Since not all properties are available in ANSYS FLUENT's Create/Edit Materials dialog box for this material type, some additional property information can be provided through the Fiber Model dialog box (Figure  3.4.1). The procedure to define the material properties for the fibers in your simulation is as follows:

1.   In the Create/Edit Materials dialog box, set the Material Type as fluid. This fluid will be used as the polymer or solvent in the fiber.

2.   Enter all data for this material.

3.   Select the Polymer or Solvent in the Materials group box of the Fiber Model dialog box.

4.   For dry spinning simulations, you also have to select the gas phase species which represents the Solvent Vapor.

5.   Enter any additional data needed for the fiber material in the Fiber Model dialog box.

You can use all profiles available in the Create/Edit Materials dialog box to define the properties as functions of temperature, except user-defined profiles.
