Progress towards a suite of integrated codes for computing the mutual interaction of ICRF antennas with the turbulent scrape-off-layer (SOL) plasma is described. The rf waves are calculated by the 2D MORRFIC antenna code, modified to include a vacuum sheath boundary condition; the SOL profiles are evolved using the SOLT 2D turbulence code, modified to include nonlinear sheath and ponderomotive physics. The SOLT code includes the physics of 2D turbulence, blob transport, rf convection, and ponderomotive density depletion. Iteration of these codes to convergence would provide self-consistent solutions for the density and the rf waves. Finally, an rf sheath boundary condition is described, which permits an iterative solution for rf fields at the boundary and the associated sheath potential and sheath power dissipation. Physics results and future plans for code integration are discussed.
