WebPNEWDT denotes a factor that can be modified in the UMAT routine to be less than one, to signal a cut in the time step, or more than one, to signal a local increment in the time step. Since these time step controls are local to the quadrature point, MOOSE provides a layer of objects to handle the information provided by UMAT's PNEWDT .
