This command is used to update the parameters of PressureDependMultiYield or PressureIndependMultiYield material. Currently, two material parameters, reference low-strain shear modulus Gr and reference bulk modulus Br, can be modified during an analysis.
Please visit http://cyclic.ucsd.edu/opensees for examples.
