Flow along surface truncated cone

Hi there,
I am trying to flow along a surface that is not rectangular and have no idea how to go about it!
I have flowed many things before but they are always on surfaces that unroll to be rectangular and I am not sure of how to get my rectangular shape to fit the curved surface that is the unrolled surface from the truncated cone. Thanks in advance!

Hello - I can’t tell what the desired result is - is it this?


yes @pascal except the other way around- with mountains pointing towards the larger end rather than the smaller end.

Hello - so FlowAlongSrf - click one edge of the base surface and the corresponding edge of the target, with AutoAdjust set to Yes.
