Syntax errors with Thread Types and Wall Heat Transfer calculation

Hello,
I am trying to let Fluent calculate the temperature of a wall that gives a certain heat flux at the end of the calculation. First i run some iterations with a constant temperature at the wall and then I compile (interpreted) the udf and assign it to the wall temperature. The code looks like this: #include"udf.h"The line "if(THREAD_TYPE(f_thread) == THREAD_F_WALL)" does not work. I thought it should be quite easy to verify if a thread is a wall, but I always get the error message "structure reference not implemented". Maybe it has something to do with the installation or the version. I use Fluent 13.0.0. The macro BOUNDARY_HEAT_FLUX(f,f_thread); gives after 1 iteration "access violation" as output and I have to restart FLUENT. Finally abs() doesn't work either, since there is no math.h file in the src directory. Any idea how to overcome this? I would be very thankful, if someone could help. Thanks in advance and best regards. J. |

Sorry, the calculation of the correction factor is missing in the code.
There is a line looking like this between the two big loops: alpha = curr_heat / end_heat; |

what does this statement mean?
if(THREAD_TYPE(f_thread) == THREAD_F_WALL) |
