We are constructing theoretical models of the disk-like circumstellar material surrounding classical Be stars. These models include a self-consistent thermal structure plus pressure structure perpendicular to the equatorial plane.These models are constructed in an iterative manner by solving the atomic level populations based on balancing energy terms at various positions within the circumstellar envelope. This process is repeated to consistently enforce hydrostatic equilibrium perpendicular to the disk.This technique is the first attempt to produce theoretical models with both a self-consistent thermal and pressure structure. These models are used to investigate the influence of the disk geometry, including possible flaring at large radii, on the predicted spectral energy distributions.
