So, which help do you want? Do you want help in how to make the UDF? Help in getting the UDF that you already made to work? Or just mental support?

If the Fluent manual is not good enough, how can we help?

I am not saying we can not help, but you should give something to work with... What do you want from us? What did you miss in the manual?

Write down what the UDF should do.
Break this into smaller and smaller steps.
Do this a few times, until you can not break it down anymore.
In the ends, the steps will be so small that you can translate it to a UDF, and many people here can help with that last part.

Example:
Step 1:
Code:
The UDF should make a cake.
Step 2:
Code:
The UDF should buy ingredients for a cake;
mix them in the right proportions;
and bake the cake in the oven
Step 3:
Code:
The UDF should buy:
  *500 gr. flour,
  *10 eggs,
  *400 gr butter,
  *250 gr sugar.
Then mix the flour with the butter and the sugar,
and add 10 eggs to the mix.
Then put the mix in the baking mold.
Then put the baking mold in the oven,
set the oven to 180 degrees,
and let it wait for 40 minutes,
and then take it out of the oven.
Don't think this is a joke by the way: this is how coding works. Break complex things down, until you are at a level that the computer can understand.

You are lucky that it did not work. From the post history of Vania, it looks like she/he was trying to get people to download malware.

Hi, Config,

I am trying to simulate a leaf falling down the tree.
Is the udf you had posted is sufficient to describe the leaf motion for a six-dof solver? @@
Thank you!

#include "udf.h"
DEFINE_SDOF_PROPERTIES(proj, prop, dt, time, dtime)
{
prop[SDOF_MASS] = 1;
}
the other progress of solve is in "projectile moving inside a barrel"pdf that you want it i can send it for you
