In the pre-analysis, the maximum stress was calculated. In order to verify that our simulation was accurate, a comparison must be made. In order to calculate the maximum stress of the simulation, click on Add next to Results, and select Calculated Value. In the function drop down menu, select Maximum. Under the Variable drop down menu, select Equivalent Stress then press Evaluate. Very quickly, the maximum stress of the heated bar is calculated and displayed. This maximum value can also be seen in the panel on the left when the Equivalent Stress 1 contour is displayed.
The table below compares the calculated and simulated values for maximum stress in a heated bar. With a difference of much less than 5%, we can consider our simulation to be accurate.
