updateParameter

This command is used to update material 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.

To update G_r:

updateParameter -material $tag -refG $newVal

To update B_r:

updateParameter -material $tag -refB $newVal
