read boundary conditions with udf
 

hi, i wrote a little udf that helps me with the postprocessing. now i am looking for a possility to read out the boundary conditions at my mass-flow-inlet (temperature and mass-flow-rate). i need this data for an if-else statement within my udf. how can this be done? i tried it with F_FLUX in a thread_f_loop. but that does not give me the correct mass-flow. do i always need to put F_FLUX into a thread_loop_f? because i always get a segmentation violation if i use it standalone.
