The hydrodynamic response of the solar atmosphere to the injection of an intense beam of electrons in a numerical simulation of a solar flare is calculated. The spectroscopic consequences of the hydrodynamic behavior thus calculated is then predicted. Prediction of the hydrodynamics is done by solving the equations of conservation of mass, momentum, and energy. The results reveal how the loop is filled at supersonic speed with plasma at temperatures characteristic of flares. At the same time it is predicted that a compression wave will propagate down toward the photosphere. Once the heating pulse stops, the plasma that has risen into the loop starts to decay and return to the condition it was in before the pulse started. Calcium is chosen for illustration in predicting the spectrum that would be emitted by such a plasma. The first and main part of this calculation involves setting up and solving the time-dependent equations of ionization/recombination. To provide a standard for comparison, the same ionization and recombination rate coefficients are used to predict the steady-state distribution of populations of ionization stages.
