ABSTRACT=The study of modified cross model (MCM) fluid flow around the circular obstacle with 
symmetric trapezoidal cavity isinvestigated by numerical  computing. Momentum equation 
elucidating the flowing features of (MCM) has been solved by implementing finite element 
method (FEM) for range of: power law index (m) 0 to 5, Reynold number is fix for Re=20 and 
modified parameter (b) from 0.0 to 0.5. Domain discretization at coarse level is performed by (
21 PP ) shape functions. In addition, (MCM) fluid considers parabolic profile for inlet velocity 
also the Neumann condition is placed at outlet of channel. Circular obstacle is placed at (2, 1) 
middle of symmetric cavities. Fluid forces like drag and lift variations are measured, also 
evaluates the line velocity profile for different values of m at several positions.
