Hi, I am getting a segmentation fault for this UDF, can someone help me out ?


#include "udf.h"

DEFINE_DPM_LAW(att1,p,ci)
{
Domain *d;
Thread *t;
cell_t c;
real cell_no=0;
real sum_dens;
real avg_dens;

thread_loop_c (t,d)
{

begin_c_loop_all (c,t)
{
sum_dens+= C_R(c,t);
cell_no=cell_no+1;
}
end_c_loop_all (c,t)
}

avg_dens=sum_dens/cell_no;

printf("Average density=%g\n",avg_dens);


}

}

you are pointing to the domain d but are not defining it. add the following line to your code

d = Get_Domain(1);

Yeah I added that , thanks. I am having some problems compiling udfs in Windows 10. I can build them but it shows an error "libudf.dll" missing. Is anyone else getting the same error ?
