You want to simulate using a constant value of radiation in the first case?
Meanwhile, you may want to explore the solar load model of fluent: 14.3.11. Solar Load Model (
For the second case maybe you could try using expressions in an appropriate radiation model
14.3.1. Using the Radiation Models (
5.3. Creating and Using Expressions (
Hope it works.
