Total Velocity
Hi,
May be a stupid question? I have U and V velocity, I dont have total velocity (after loading data into tecplot from CFX output--cngs) How can I obtain in tecplot total velocity and make contour of it? In Equation it seems I am allowed to only define scalars? Magnitude I can define, but I want to visualise also some flow reversal, total velocity? Thanks, |
Velocity magnitude is available by default in CFD-Post. Looks like in tecplot you don't get it. You will have to define velocity magnitude as an equation, as a function of U, V and W. Then it will be a scalar variable that you can do what you like with.

But the problem remains the same.
Mag=sqrt(u²+v²+w²); then it takes always positive values. I just want to have Total_Vel=u*i+v*j+w*k, i,j,k---unit vectors Thanks |
? Of course Velocity Magnitude is always positive. It is the magnitude of a vector.
I don't know tecplot too well so don't know how they deal with vectors. Generally when you set up a vector field object you define what scalar variable it is to take the X, Y and Z components from. I am sure tecplot will be the same. |
I think tecplot should be able to draw contour of velocity magnitude basing on the velocity vector. Are you sure it's uncapable of that?
