Hi All,
There is a system of equations arising from the discretization of 3D
incompressible Navier-Stoke equations using a finite element method. 4 unknowns
are placed on each mesh point
Hi All,
There is a system of equations arising from the discretization of 3D
incompressible Navier-Stoke equations using a finite element method. 4
unknowns are placed on each mesh point, and then there is a 4x4 saddle
point block on each mesh vertex. I was thinking to solve the linear
equations
