Model optical property degradation

1. Create Thermo-Optical Properties - State modeling objects.States model different thermo-optical properties of the same material, such as optical properties at the beginning of life and at the end of life, using existing Thermo-Optical Properties or Thermo-Optical Properties - Advanced modeling objects. Each Thermo-Optical Properties - State modeling object can reference up to five Thermo-Optical Properties or Thermo-Optical Properties - Advanced modeling objects.Choose Home tab→Properties group→Modeling Objects .In the Modeling Objects Manager dialog box, from the Type list, select Thermo-Optical Properties - State.Click Create.In the Thermo-Optical Properties - State dialog box, from the State 1 list, select existing thermo-optical property modeling objects or click Open Manager to create a new thermo-optical property modeling object.For more information, see Define thermo-optical properties.Repeat step d to create other states.Click OK.In the Modeling Objects Manager dialog box, click Close.

2. Reference the created Thermo-Optical Properties - State modeling objects in the appropriate mesh collectors.

3. Create your boundary conditions and solution.

4. Specify the thermo-optical property state that you want to use.In the Simulation Navigator, right-click the solution node and choose Edit.In the Solution dialog box, click the Thermal page.In the Thermo-Optical Property State box, type the number of the desired state.The state number indicates which thermo-optical properties defined in the Thermo-Optical Properties - State modeling objects the thermal solver uses during the solve. By default or when an optical property does not exist for a specified state, the thermal solver uses the thermo-optical properties from the first state.Click OK.

5. Solve your solution.

6. Clone the solution, make any changes to the new solution, and modify the state for the new run.

7. Solve the cloned solution.

8. Repeat steps 6 and 7 for all other states.
