WebFor simplicity we take κ =1 κ = 1. In cylindrical coordinates, the Laplace operator becomes ( r r is the distance to the axis, z z is the distance along the axis, θ θ polar angle in a fixed plane perpendicular to the axis): Δu = 1 r ∂r(r∂ru) + 1 r2 ∂2 θθu +∂2 zz. Δ u = 1 r ∂ r ( r ∂ r u) + 1 r 2 ∂ θ θ 2 u + ∂ z z 2. WebA projection algorithm for the Navier-Stokes equations. Summary : Fluid flows require good algorithms and good triangultions. We show here an example of a complex algorithm and or first example of mesh adaptation. where uoX(x) =u(x −u(x)δt) u o X ( x) = u ( x − u ( x) δ t) since ∂tu+u⋅ ∇u ∂ t u + u ⋅ ∇ u is approximated by the ...
