Validation

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 and under the Variable drop down menu select Equivalent Stress then Evaluate. Very quickly the maximum stress of the heated bar is calculated and displayed.

The table below compares the calculated and simulated values for maximum stress in a heated bar. With a difference of less than 5% we can consider our simulation to be accurate. This small difference in results may be caused by the simplification process.
