Once a structure has displaced, the forces act on a geometry that is different than the geometry that was initially analyzed. Secondary forces develop due to eccentricities created by these displacements. These secondary forces are known collectively as P-(U+0394) and P-(U+03B4) effects. -P-(U+0394) effects are secondary forces that develop due to the displacements of nodes in the model, while P-(U+03B4) effects are secondary forces that develop due to member displacements. +P-:math:`\Delta` effects are secondary forces that develop due to the displacements of nodes in the model, while P-(U+03B4) effects are secondary forces that develop due to member displacements. There are traditionally 2 types of procedures used to run P-(U+0394) analysis: 1. The iterative procedure - A basic analysis is rerun considering the effects of the displaced goemetry, leading to further displacements. These further displacements require further iterations until the displacements either converge or diverge.
