[CIG-SHORT] fault traction perturbation

[Birendra jha]

Hi

My question is with regard to the implementation of traction perturbation in dynamic faulting code. Traction perturbation is considered in the assembly of the residual (integrateResidual). However, it does not play any role anywhere else, especially in the solution correction steps. Is that correct? One of the correction step is "Insure fault traction is zero when opening." Is that still true when there is a positive traction perturbation? 

Thanks
