How to define the absorptivity in In Acuconsole and Earth Albedo and Earth IR Flux?

Hi Nagapp,

First enable the "Heat Transfer" toggle in the Solution dialog box.

In SimLab, the value of absorptivity is automatically set based on the values of transmissivity and reflectivity. Don't need to specify it separately.

For the Earth Albedo and IR flux, I believe it can be specified using the "External Radiation" dialog as shown below.

Hope it helps.
