Here we show how an anisotropic

uid in the di usion limit can be equivalent to an isotropic

uid in the streaming out limit, in spherical symmetry. For a particular equation of state this

equivalence is total, from one

uid we can obtain the other and vice versa. A numerical master

model is presented, based on a generic equation of state, in which only quantitative di erences are

displayed between both non{adiabatic

uids. From a deeper view, other di erence between

uids

is shown as an asymmetry that can be overcome if we consider the appropriate initial{boundary

conditions. Equivalence in this context can be considered as a rst order method of approximation

to study dissipative

uids.
