Hello all,

I want to print a variable in a UDF hooked to a BC in my case. However, in each iteration, the message printed several times:

BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]
BC Pressure: -1.19 [Pa]

I think the UDF called several times in each iteration and that's why it printed several times.
Any idea how can I call "printf" only once, no matter how many time hooked UDF to the BC called?

Thanks.

in the face loop, add
if(f==0)
printf(xxxxxxx);
