In this sample session, you will use Ansys Polymat to find the correct parameters for the power-law model for the fluid with the behavior described in Problem Description. There are two fitting methods available in Ansys Polymat, and you will use both of them in this example. In the first (non-automatic) method, you will change the value of one parameter at a time until you find the best fit. In the second (automatic) method, Ansys Polymat will calculate the best fit for you. Each of these methods is outlined in Steps for Fitting Material Parameters and described in more detail in Fitting Material Parameters.

Using the Non-Automatic Fitting Method shows how to perform the fitting in this example using the non-automatic method, and Using the Automatic Fitting Method shows how to perform automatic fitting.
