Member Data Documentation

◆ Default_residual_multiplier

double oomph::HijackedElementBase::Default_residual_multiplier =0.0

staticprotected

Static default value for the double that multiplies the original residuals.

Static default value of the multiplier for the original residuals The contribution to the total residuals is the product of the multiplier and the original value of the residuals
