I have geometry look like cylinder ,within that lot of obstructions were there.

what i need is curve wich reperesents v= f(x); here x is axial direction distance .and velocity represents avg velocity at particular distance within the domain.

plz suugest me regarding this.

Thank you

kk

surface > line/rake

Thank you Joe,

but what I wanted is plane wise avg along the axis and get afunction.

for example flow in cylinder with some cooling coils.

so temperature of fluid drops continuosly and density will icrease. so velocity will vary along the path.

I want to know how it is varieng with distance.

if i use line or rake it is like tracing point along the axis.

if we sweep point we get line/rake. here I wanted to sweep surface or plane to cover entire volume.

is there any way to get function, udf or tui any thing?
