We assume a single open magnetic flux tube spanning the solar photosphere and the lower corona in magnetohydrostatic equilibrium within a realistic stratified atmosphere subject to solar gravity. We explore and discuss variants of self-similar flux tubes including twisted magnetic fields. The aim is to apply this model as the background condition for numerical studies of energy transport mechanisms from the solar surface to the corona taking suitable inputs of magnetic field strength, plasma density, pressure, and temperature distributions consistent with observations.
