"Average Error (per node)" 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.
Increasing the "Axial Stiffness" of the simulation will tighten these constraints and
lower the error in the simulation.
To visualize the error of each node graphically, select "Node Error Material" under "Mesh Material"
in the left menu.
