Hi,
I am trying to add extra mass source through UDF but getting this ERROR MESSAGE:
Node 0: PROCESS 15088: Received signal SIGSEGV.
Node 1: Process 16164: Received signal SIGSEGV.
MPI Application rank 0 exited before MPI_Finalize() with status 2
The fl process could not be started.
The UDF code is as below:
DEFINE_SOURCE(mass_source, c, t, dS, eqn)
{
real source = 0.0;
real mass_source = 0.0;
real area_vec[ND_ND];
real area = 0.0;
int n;
real v=0.0;
real rho=0.0;
c_face_loop (c, t, n)
{
Thread *tf = C_FACE_THREAD (c, t, n);
real SURFACE_ID = 6;
if(SURFACE_ID == THREAD_ID(tf))
{
face_t f = C_FACE (c, t, n);
F_AREA(area_vec, f, tf);
area = NV_MAG(area_vec);
rho=C_R(c,t);
v=C_VOLUME(c,t);
mass_source = (-(C_YI_RG(c,t,0)[1]*C_DIFF_EFF(c,t,0))* ((1/C_YI(c,t,0) )-1))*rho*area/v;
source += mass_source;
}
}
C_UDMI(c, t, 0) = source;
dS[eqn] = 0.0;
return source;
}
Can anyone suggest on this error?
try like this:
DEFINE_SOURCE(mass_source, c, t, dS, eqn)
{
#if !RP_HOST
real source = 0.0;
real mass_source = 0.0;
real area_vec[ND_ND];
real area = 0.0;
int n;
real v=0.0;
real rho=0.0;
c_face_loop (c, t, n)
{
Thread *tf = C_FACE_THREAD (c, t, n);
real SURFACE_ID = 6;
if(SURFACE_ID == THREAD_ID(tf))
{
face_t f = C_FACE (c, t, n);
F_AREA(area_vec, f, tf);
area = NV_MAG(area_vec);
rho=C_R(c,t);
v=C_VOLUME(c,t);
mass_source = (-(C_YI_RG(c,t,0)[1]*C_DIFF_EFF(c,t,0))* ((1/C_YI(c,t,0) )-1))*rho*area/v;
source += mass_source;
}
}
C_UDMI(c, t, 0) = source;
dS[eqn] = 0.0;
return source;
#endif
}
then just compile the udf file, don't interpret it.
Hi,
Thanks for the code. I compiled and tried to load the udf but I am getting the following error:
"The UDF library you are trying to load (libudf) is not compiled for 2ddp on the current platform (win64).
The system cannot find the file specified."
when you press the 'build' button, what is shown on your screen? perhaps there's an error during the compiling section of solution!
Greetings Mr. Hasibul, Can you please explain on how you sorted your memory location problem ?
Hello Mr. Hasibul Alam,
I face the same problem of ""The UDF library you are trying to load (libudf) is not compiled for 2ddp on the current platform (win64)" . Can you tell me please how did you solve it?

Hi Dawood,
You need to install MS Visual Studio. The version should match the requirement for the Ansys version. It worked for me.
Hi Mr Hasibul;
I face the same problem of ""The UDF library you are trying to load (libudf)... ;I install visual studio but i have the same problem.!!! I have Ansys 14.5 and 15; what is the appropriate version of visual studio to install.
Thanks in advance
