This paper provides an accurate and simple simulation workflow for Structural, Thermal and Optical Performance (STOP) analysis on complex optical systems. Applying this workflow to a high-power laser system, we use Ansys Zemax OpticStudio for both optical design and wavefront analysis. Then Ansys Speos is used for optical heat load calculation on each component of the system. Finally, Ansys Mechanical is used to perform thermal and structural analysis, providing this information back to OpticStudio for wavefront error analysis and optical tolerancing. The workflow is fully automated thanks to Ansys System Coupling interface. Besides the ease of use, this workflow captures the impact of structural deformations and refractive index changes on the key performances of any optical system, accounting for opto-mechanical component contributions. The approach can be steady-state or transient.
