Hi fellows,
I am trying to run UDF on a linux based machine with shared memory by parallel processing (16 processors).but i got the following error,

Error: The UDF library you are trying to load (libudf) is not compiled for parallel use on the current platform (lnia64).

No such file or directory
/data1/home/mehmood/fluent/3dAbid/libudf/lnia64/3ddp_host/libudf.so
Error Object: #f


Error: CAR: invalid argument [1]: wrong type [not a pair]
Error Object: ()

my UDF is as under,

#include "udf.h"

DEFINE_PROFILE(velocityinletw , thread, position)
{

float t, velocityw;
face_t f;

t = RP_Get_Real("flow-time");

velocityw = (3.14*0.01*1.4*0.496*cos(2*3.14*1.4*t));
begin_f_loop(f, thread)
{
F_PROFILE(f, thread, position) = velocityw;
}
end_f_loop(f, thread)

}

can any one help me in sorting out this problem.
est Regards

Your program a UDF for paralell use, and I see your defining a profile, you can run the UDF in serial processing and then write the profile on the section your applying the UDF. Then open a new fluent case and you can read the profile instead of using the UDF. Ive done that but my profile was on stedy state and dont change. Good look.
