An algorithm is given for calculating the fictive temperature of glass based on the differential form of Narayanaswamy's equation. This algorithm is more convenient and much more efficient than direct solution of the integral equation and has been implemented in viscoelastic stress analysis using finite‐difference and finite‐element methods.
