I am trying to use the Battery addon module for Fluent, but the Parameter Estimation Tool doesn’t appear to be working. I get the same result in v 17.2 and 18.2. All the parameters come up as -1.#IND00e+00.

      The parameters the module is fitting are 5th order polynomials. When a fit is not achieved, the mostly likely cause is that not enough voltage time data has been provided. While the minimum is 2 V-Time curves at different C rates, 5 curves are recommended. If there is an error in the data, such as a typo that has produced an outlier point, this may also prevent the fit from being successful. Please see the attached document for more information on the Parameter Estimation Tool
