[交流] FLUENT UDF HELP上面的一个UDF例子

#include "udf.h"

Thread *t = Lookup_Thread(domain, id);

begin_f_loop(f,t)
{

fprintf(fout, "f%d %g %g %g\n", f, FC[0], FC[1], FC[2]);
}
end_f_loop(f,t)
fprintf(fout, "\n");
}
DEFINE_ON_DEMAND(get_coords)
{
Domain *domain;
domain = Get_Domain(1);
fout = fopen("faces.out", "w");
Print_Thread_Face_Centroids(domain, 10);

fclose(fout);
}
