Hi everyone
I'm modelling a process of a furnace. The heating process in this furnace occurs gradually, i.e. the thermal profile is changing with time. I have managed to write a UDF for this transient temperature for the furnace wall. Now I want to monitor the temperature profile of the product inside the furnace, which will be also changing with time as the heating process is running.
Now I want to capture the product's transient temperature at every time step and use it in post processing to make a temp. vs time graph?
What MACRO or SCHEME MACRO can I use to get this temp. variable from the UDF in such a way that I can use it in post processing. Also Can I save the output parameters in a file that can be opened in excel or MatLab?
Please see below code which is I believe not so correct as I built it using different tutorials. Please have a look and advice me how to modify it. I also want the values of the temperature and to be saved in a file that can be opened in excel, if possible.
/* Compute face average temperature and store in user-defined memory */
#include "udf.h" #define ID 8 DEFINE_ADJUST(wall_temp,domain) { face_t f; Thread *t = Lookup_Thread(domain, ID); begin_f_loop(f,t) { temp = F_T(f,t);
F_UDMI(f,t,0) = (temp - tmin) / (tmax-tmin);
} end_f_loop(f,t) }
Any help is much appreciated Oula
No need to write udf. Define the variable in custom field functions. Then select it in monitor output. Select the write option. Open file in excel
