*SetMaterialProperty() - NeoHookean-Incompressible

Sets the hyper elastic Neo-Hookean Incompressible material property for a large deformation body.

Syntax

*SetMaterialProperty(varname, NHI, shear, poisson_ratio, density_rho)

Arguments

varname: The variable name of the material property.; Data type: varname
