The results from the graded mesh will be compared with those from the previous meshes. STAR-CCM+ User Guide Steady Flow: Lid-Driven Cavity Flow 9 Version 7. The calculations of energy and. Tech Student 2Dean Academic and Head ME 3Assistant Professor 1,2,3NITM Gwalior Abstract—This project aims at simulating lid driven cavity flow problem using package MATLAB. The fundamental feature of this often studied fluid flow problem is the formation of a large primary vortex in the center and two smaler vortices near the two lower edges. The lid-driven cavity flow is probably one of the most studied fluid problem in the field of computational fluid dynamics.
