In order to deal with the problem of accretion disks around black holes, numerous models have been introduced during the past five years. The present paper is in particular concerned with the models discussed by Paczynski and Abramowicz (1982), taking into account a reproduction of the numerical integrations. Attention is given to details regarding the integration of the differential equations, the interior structure, model refinements, and cusp energetics. It is concluded that the structure of thick accretion disks of the type proposed by Paczynski and Abramowicz is extraordinary sensitive to the conditions at large radii. At some places in parameter space, only a minute change in the starting values separates two very different families of solutions. It is speculated that the solutions are globally unstable, even though they are stable to local axisymmetric perturbations by the Hoiland criterion.
