How to control the time step and iteration for summation?
 

Hi,

I need to sum a variable per each time step while not sum per each iteration. the UDF is like the following:

if (N_TIME==1)
{
sum=C_UDMI(c,t,0);
N=0;
}
else if (N_TIME==N)
{
sum+=C_UDMI(c,t,0);
}
...
N=N_TIME+1;

It does not working. What's wrong?

Thanks in advance

I mean, the UDF did not do the summation.

Compile and hook it.
