One-dimensional heat transfer is assumed along the model length, a, which is chosen such that no significant change in temperature occurs at the end region. This is done to ensure an infinite length approximation. The model width, b, is chosen such that the element aspect ratio remain constant for all test cases. 2. Time step optimization was activated to automatically increment the time step during the solution. The minimum ∆t increments chosen were arbitrary. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 2–27 Benchmark C7 3. Results tabulation includes the cumulative number of iterations per run. From these results it is shown that the time step opened up from the initial value, for the ∆t = 0.5 and 0.0667 cases. 4. All three elements are shown to conv...
