DT_CG use
 

i want to know the position of CG for this i use in my udf the DT_CG(dt)


for( i=0 ; i<3; i++)

x_cg = DT_CG (dt) ;

where x_cg habe been declared as a real .

message error (" impossible de convertir de 'real *' en 'real' ")


can someone explain me how to use correctly DT_CG ?


thanks !

DT_CG is a vector (with 2 or 3 dimensions).
So you should also define x_cg as a vector.

real x_cg[ND_ND];

And then assign it using:

NV_V(x_cg,=,DT_CG(dt));

I think.

ok i will try


at first i declared x-cg like that " real x_cg[3) " to have a vector 3dim

than i use a loop to define x-cg[i]=Dt-cg(dt) [i]
