WebThe paper presents a general framework for developing the analytical sensitivities of the STOP prediction using the Chain Rule. The paper focuses on solving for the sensitivities … A STOP model involves a coupling between the following: 1. Temperature calculation, using the Heat Transfer in Solidsinterface or another heat transfer interface 2. Structural deformation modeling, using the Solid Mechanicsinterface or another structural physics interface 3. Ray tracing, using the … See more In this example, we consider a Petzval lens system inside of a thermovacuum chamber. The vacuum chamber walls are maintained at a very cold temperature (perhaps to mimic the effects of outer space), while the lens … See more Next, let’s consider the example of a STOP analysis for a Petzval lens systeminside a thermovacuum chamber, as described earlier. The heat transfer is modeled using the Heat Transfer in Solids interface for conduction and the … See more Rays are released into the chamber at three different field angles. A ray diagram showing the temperature in a cross section of the lens … See more Above, we have demonstrated a STOP analysis of a Petzval lens system enclosed in a cold thermovacuum chamber. A temperature gradient is observed in the lenses because the system is exposed to a much warmer … See more polyethylene glycol 6000 usp
