ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–252 VM113 Analysis Assumptions and Modeling Notes A nonuniform grid (based on a geometric progression) is used in both X and Y directions to model a quarter of the bar cross-section. Automatic time stepping is used. The initial integration time step = (3/3600)(1/40) is greater than (δ2/4α), where δ is the shortest element length (0.0089 ft) and α is the thermal diffusivity (ky/γc = 1.0 ft2/hr).
