Detailed Description

Compute the solar force and torque on a thin membrane using a combined optical/thermal model.

This model is designed to connect to the geometry reader via outlets.

This is a single-sided model. If the cosine of the angle to the light source is negative, the face is assumed facing away from the sun and the force on that face is zero.

The SPICE outlets are optional.
