Hello everybody,

I wrote a UDF where I want to write the temperature values from an Array into a .txt-file:

DEFINE_ON_DEMAND(export__temp)
{
cell_t c;
Domain *d = Get_Domain(1);
FILE *temp__piece;
real temp1;

Thread *c_thread= Lookup_Thread(d,3);
temp__piece=fopen("temp__piece.txt","w");

begin_c_loop(c, c_thread)
{
temp1 = C_T(c,c_thread);
fprintf(temp__piece,"%g \n",temp1);
}
end_c_loop(c, c_thread)
fclose(temp__piece);
}

The UDF works - but the temperatures do have between 0-3 decimal places. The textfile will be exported and used for Ansys Classic further.
The problem is now: If a temperature has 0 decimal places, Ansys Classic calculates wrong (Temperature that is used then is just 1/100 as high as in the .txt-file). Therefore, I would like Fluent always to use the same number of decimal places (3).

Is that possible and can someone explain me, how this might work?


Kind regards,
Sarah
