Hi,
I want to plot dean vortices inside a 90 degree pipe bend at different section (30 degree, 60 degree etc.). The pipe bend axis rotates from y-axis to x-axis from 0 to 90 degree. I have already plotted vortices at bend outlet (90 degree) and in the downstream region by using vector plot and streamtraces option available in tecplot of x-velocity and z-velocity. But what will be the vector variables for plotting that inside 30 degree of bend section as the bend rotates about z-axis, i.e from y-axis to x-axis? Should I have to create new variables of velocity components? Hope my problem is clear to all.
