So if I run a lid driven cavity flow for a square domain and a Re of 100 and take the velocity at x = 0.5, I find that there is an inflection point near the upper moving wall using a 3 point and a 5...

Replies: 9 discontinuous second derivative Views: 2,009 Posted By new_at_this discontinuous second derivative I am calculating the first and second derivative of a velocity profile. I am using a 3 point centered for the 1st derivative and 5 point central stencil for the 2nd derivative. For some reason I...
