  In this article, we study the form of deviation of geodesics (tidal forces)
and Raychaudhuri equation in a Schwarzshild-Finsler-Randers (SFR) spacetime
which has been investigated in previous papers. This model is obtained by
considering the structure of a Lorentz tangent bundle of spacetime and in
particular the kind of the curvatures in generalized metric spaces where there
is more than one curvature tensor, such as Finsler-like spacetimes. In these
cases, the concept of the Raychaudhuri equation is extended with extra terms
and degrees of freedom from the dependence of internal variables as the
velocity or an anisotropic vector field. Additionally, we investigate some
consequences of the weak field limit on the spacetime under consideration and
study the Newtonian limit equations which include a generalization of the
Poisson equation.
