Default How to use F_FLUX_M1 macro????
Posts: n/a
Hi all;

There is a macro calling F_FLUX_M1 for calculating face flux in previous time step . But whenever i use from this macro, I am encountered Access violation error. How can i remedy this problem? Erroe takes place in this lines in UDF presented in following:

thread_loop_c(t,domain) { int i=1; begin_c_loop(c,t) ; { C_UDMI(c,t,1)=0.0 ; c_face_loop (c,t,i) { f= C_FACE(c,t,i) ; tf= C_FACE_THREAD(c,t,i) ; C_UDMI(c,t,1)=C_UDMI(c,t,1)+F_FLUX_M1(f,tf); } } end_c_loop (c,t) }

Please help me.

Thanks in advance for everybody reply my question .

remove the line where you set i=1; in C the array index starts from 0. And also because C_FACE_THREAD returns a pointer, check the pointer returned (for example if((tf=C_FACE_THREAD(c,t,i))!=NULL) { bla bla } And also I think you should use C_UDMI(c,t,0) and not C_UDMI(c,t,1) Regards
