Nor is is possible for structures to shield one another from the effects of the fluid. The contributions of each rod are treated in series, one after another. This means that the first rod is likely to have a greater effect than subsequent ones on the resulting motion of the node. Because of quantisation issues, the restorative force should have diminishing effects as it grows in magntude. The model has been implemented in both two and three dimensions.
Work now centres around the three dimensional version.
Two dimensional variants can be constructed by fixing the Z coordinate at zero. The distance from each node to the centre of gravity of each triangle could also be taken into consideration. When considering implementation details of such a model in 3D, it can be helpful to note that all the action takes place in a two-dimensional plane, defined by the two vectors corresponding to the rod and the velocity of the node. After obtaining orthogonal unit vectors that define this plane, all forces can be resolved within it, and the two-dimensional force model can then be applied without further modification.
