This paper is the first in a series of publications which investigate the stability properties of the complete set of isothermal protoplanetary equilibrium solutions. To perform a non‐linear stability analysis, we introduce a fluid dynamics numerical model. We inspect the entire solution set and find five basic dynamical modes: oscillation, pulsation, transition, ejection and collapse.
