To save a material data file so you can use it in setting up a problem in Ansys Polydata, click the Save in a Material Data File menu item in the top-level Ansys Polymat menu.

  Save in a Material Data File

Note that Ansys Polymat will save a material data file automatically after it performs automatic fitting. See Automatic Fitting for details.

If you have saved a material data file from Ansys Polymat (or from Ansys Polydata), you can read it into Ansys Polymat by clicking the Read a Material Data File menu item.

  Read a Material Data File

Reading in an existing material data file is a convenient way to start a related fitting analysis. For example, you can use the relaxation times and corresponding partial viscosities of a given model to perform a fitting analysis to find nonlinear parameters. You can also read in an existing material data file in order to draw the property curves for the model (for example, viscosity vs. shear rate) and possibly compare them with experimental data.
