Hi everyone...
Could someone please explain me why you add the GLOBAL VARIABLE X : X t - Xdo t. ?
The physics of the problem only state the necesity to establish the equation
Xdo t: Xdo tt-(F_z+F_g)/m_grain.,
which corresponds to the Ordinary Differential Equation:
(m_grain) * (Xdo tt) = (F_g+ F_z)
or
(F_g+ F_z)/(m_grain) - (Xdo tt) = 0 ; as is supossed to be entered in the software
The systems uses cylindrical coordinates so there is no conflict in x,y,z,t or X,Y,Z,T.
Thanks for your help on beforehand
Kind regards
