The finite-element method is applied to describe the 
slow flow (Re  1) of a nonlinear-viscoplastic fluid described by the Shul'man 
rheological model, which is implemented on filling of vertical volumes 
in the gravity field. The sliding effect of the fluid near a solid 
wall (the P-effect) is taken into consideration. Numerical studies 
of the process of filling of an axisymmetric region are carried out. 
An influence of the P-effect on the hydrodynamic process of filling 
is shown.
