Modeling for H-mode pedestal dynamics requires time dependent integrated understanding of edge kinetic neoclassical and turbulence physics, core turbulence, MHD physics, large scale edge localized modes such as ELMs, neutral, impurity and atomic physics, scrape-off-layer physics, neutral recycling, and energetic particle influx from the plasma core. Wide ranges of time and spacial scales are necessary to resolve in order to predict the dynamics of the tokamak plasma edge. It is unpractical or even impossible to implement all this physics in a single code that would need to resolve the smallest spacial and shortest time scales for the prediction of plasma behavior on long transport scales. In order to address the complexity the edge tokamak plasmas, an integrated modeling approach is used in our studies. In this report, we present the results related to the modeling of the H-mode pedestal dynamics and stability, as well as the modeling of the SOL width and SOL flows using a combination of codes. These codes include the neoclassical kinetic XGC0 code, ideal MHD ELITE code, and extended MHD NIMROD code.
