time steps count
 

Hi everybody
im writing UDF using DEFINE_CG_MOTION
I have to make at the end of calculation low pass filter of the results and i want to include the filter in the aforementioned UDF. In these case i need to know when is the end of calculation.
So the question is is there possibility to get time step count to include it in UDF

check this link

Easiest way is to use a static variable that counts number of times DEFINE_CG_MOTION is called. This works because DEFINE_CG_MOTION is called once for each time step. I would better use execute_at_end or execute_on_demand for doing this kind of operation.

Tnx for answer but i need the final count of time steps to include it in UDF

like IF count = ..... then do the low pass filter
so i need to know the number of final count to use it in UDF

follow this sample code,


DEFINE_CG_MOTION(....)
{
static int time_counter=0;
time_counter++;

if(time_counter > required_timestep)
{
.....
}

}

When i start my calculation i insert "Number of Time Steps" in Fluent.
In my case 300000.
So i need after time step 300 000 to start filter or If count=300000 do....
But this is private case and i want to make UDF for any case
when i dont know "Number of Time Steps" is there a way to obtain this number from Fluent
