I am running a form finding analysis for a draped catenary structure fro a solar array. Kangaroo has been great so far, but we are starting to need real life numbers. Mostly, we want to be able to apply real life weight, and tensile strength numbers to our panels so we can accurately model how these panels with drape and then use that geometry to accurately calculate our solar energy output. This is extra important because we are trying to optimism for cost of structure vs energy production.

Can someone explain how the “strength” input works? Like if I wanted to apply gravity (32.2ft/s/s) to a 15lb panel, what strength should I put for the force?

Thanks!
