  We use the dissipative type theory (DTT) framework to solve for the evolution
of conformal fluids in Bjorken and Gubser flows from isotropic initial
conditions. The results compare well with both exact and other hydrodynamic
solutions in the literature. At the same time, DTTs enforce the Second Law of
thermodynamics as an exact property of the formalism, at any order in
deviations from equilibrium, and are easily generalizable to more complex
situations.
