Shortcutter is on a distinguished road
first, sorry for my english.

I need to create an UDF with probably DEFINE_ADJUST which give a velocity for a step by step calculation in function of the x forces.

in fact, i need this type of thing :


and for each step :

my_velocity= my_velocity(stepbefore) - forces_X/450*dt;

But i don't understand very well how work UDF, and where i can find the name for X_force.

If you have an idea..?
