variable load along a curve

[jlrp]

Hello team Femap
I am working on a hydrofoil, I have the outputs from the hydrodynamic study that give me a distribution of load as N/mm along the span of the foil.
Therefore I am trying to apply this force/length along a curve on the surface of the foil.

First I created a function crudely representing this spanwise distribution:

in X I have the length along the curve in mm
in Y I have the load / length, in N/mm
in "type" I have tried both non-dimensional, and vs. curve length

Then I created a load along curve. I tried two options, FORCE and FORCE PER LENGTH as both offer the possibility to chose "variable"
here is the screenshot for FORCE, the results for FORCE PER LENGTH are identical

magnitude 1 because I expect this to be multiplied by the function
In both cases I chose METHOD, VARIABLE, click on ADVANCED

MULTIPLY BY: FUNCTION
I select my function

End result looks like this for both load types:

so I have a distributed load of 1N/mm along the whole length of the curve, the function is not taken into account, and the deformation results concur.

What am I doing wrong ?
Thanks in advance
Jeremy

have you tried youtube … (seriously, many of the videos help)

have you tried tutorials ?

have you tried the help desk ? (sometimes they can be very helpful)

post the final answer (so we can all learn)

another day in paradise, or is paradise one day closer ?

Well, there is this tutorial

https://www.youtube.com/watch?v=sdoQKZuqDms

which I used as a starting point, but the variable loading is equation based, not function based.
The first steps are identical I guess, but the function part is not :-(

ok, you've done the basics … I'd ask the help desk

another day in paradise, or is paradise one day closer ?
