Dimensions: (the STL file format is unitless, but typically assumed to be either in inches or mm)
"Average node error" gives a sense of how much the distance constraints in the
origami pattern are being violated. The error at each node is evaluated by averaging the
percent deviation of all its distance constraints with adjacent nodes. This error is
reported as a percent of the total length of the distance constraint to remove scaling effects.
This measurement is equivalent to
Cauchy strain or engineering strain of the axial constraints on this system.
Increasing the "Axial Stiffness" will tighten these constraints and
lower the error in the simulation.
To visualize the error of each node graphically, select "Axial Strain Visualization" under "Mesh Material"
in the left menu.
