I have known that marco C_U(c,t)can return the u veloicty recorded at the centroid of cell. But does it mean the x component of velocity under cartesian c.sys? Otherwise, the axial velocity of the fluid? (The axis defined in the fluid panel)

hi

U =x velocity V = y velocity W = z velocity

NV_MAG(vel)= magnitude velocity

NV_D(vel,=, C_U(cell,thread),C_V(cell,thread),C_W(cell,thread) );

NV_MAG(vel);

regards

Alex

Dear Alex,

Does "NV_D" in "NV_D(vel,=, C_U(cell,thread),C_V(cell,thread),C_W(cell,thread) ); " mean the dot product of the C_U(c,t), C_V(c,t),C_W(c,t)?

BTW, the return of C_U(c,t) or C_V(c,t)is a vector not a scalar (magnitude), isn't it?

Hello Alex,

I figure out you might be able to help me

I'm trying to return the angular coordinates of my rotating disk in form of degree between 0 to 360. However I found out that by selecting the angular coordinates, I was left with 2 part of 0 to 180 degree rotating clockwise & anticlockwise. Is there any function that return the angular position in full revolution? Also can I directly retrieve anything in polar coordinates using existing fluent's function? (without resorting to writing UDF - I'm pretty new to FLUENT)

Thanks a lot.. and hope to hear from you...
