Conversion between gravity and mass

Grasshopper Karamba3D
1

Hi, maybe this is a stupid question.

The total weight of my model that I calculated by hand is 44.73[kN] = 4473[kg]
The Mass output of the Assemble component says 4473[kg], which matches my hand calculation. But the Gravity output of the Analyze component says 447.3 [kN], which is a mystery for me.
So I’m guessing I’m misunderstanding something about the gravity output of the Analyze component.
Please somebody help!

Thanks!

Hi @mikity_kogekoge, which version of Karamba3D are you using as the results should be as per your calculation. Can you please share your definition?

Hi, you have applied a multiplier for the force of gravity. Your gravity multiplier is 10, and therefore your reaction forces are 10x larger.

Oh, sorry that I did not reply earlier. Thank you. I completely forgot that I was setting the multiplier to 10.
