updateParameter

This command is used to update:

1. Parameters of PressureDependMultiYield or PressureIndependMultiYield material. Currently, two material parameters, reference low-strain shear modulus G_r and reference bulk modulus B_r, can be modified during an analysis.

2. Permeability parameters of solid-fluid fully coupled elements including FourNodeQuadUP, Nine_Four_Node_QuadUP, BrickUP, and Twenty_Eight_Node_BrickUP.
