Hello,

I'm using ANSYS (2021R) Steady-State Thermal simulating the heat transfer of a spacecraft's thrusters onto the rest of its thruster bay and components within.

I'd like to also consider the temperature effects that the sun may cause on my system.

Does anyone know of any good methods to simulate this effect?

Currently I'm using Steady-State Thermal, but I'm open to other Workbench analysis systems.

I'm not too familiar with anything besides Steady-State Thermal unfortunately but willing to adapt and learn.

My idea so far is to just create a sphere that will represent the Sun, but the problem with this is that SpaceClaim (CAD Software) won't let me add anything that large or that far away from my system.

If I shrink the "Sun" and move it closer, I'm not sure what to make its temperature or heat flux, since obviously if I keep it at its surface temperature, it being closer will cause a larger effect on the system.

Any help is appreciated.

Thanks.
