Hii...
I have written a simple UDF. It has used UDS and UDM. It got successfully compiled but is not undergoing calculation. The code is stated as below....


#include "udf.h"
#include "mem.h"

DEFINE_ADJUST(adjust,d)
{
Thread *t;
cell_t c;
face_t f;
real temp;
thread_loop_c(t,d)
{
begin_c_loop(c,t)
{
C_UDSI(c,t,0) = C_MU_T(c,t);
}
end_c_loop(c,t)
}
thread_loop_c(t,d)
{
begin_c_loop(c,t)
{
C_UDMI(c,t,0)C_UDSI(c,t,1) = C_UDSI_G(c,t,0);
}
end_c_loop(c,t)
}

}

As per my experience, there is problem in assigning the accurate number of scalars and memory in the USER-DEFINED panel oof Fluent. Kindly help in sorting out the problem and any other problem if any.

#include "udf.h"
#include "mem.h"
enum
{GRADT};

DEFINE_ADJUST(adjust,d)
{
Thread *ct;
cell_t c;
real temp;
thread_loop_c(ct,d)
{
begin_c_loop(c,ct)
{
temp = C_T_G(c,ct)[1];
C_UDMI(c,ct,GRADT) = temp;
}
end_c_loop(c,ct)
}
}


Similar problem is with this code also. please help...

what problem do you have?
show explicitly errors which you have

Hii Alexander...

thanks for reply.

Following are the codes and their respective errors. The codes shown the error.

1. Adjust_udm get compiled but shows error during iteration.
2. Adjust_uds does not get compiled.

		C_UDMI(c,t,3) = C_UDSI_G(c,t,0)[2];
    }
    end_c_loop(c,t)

fluent GUI -> user-defined -> memory -> ud memory locations -> 4
fluent GUI -> user-defined -> scalars -> uds -> 1
