Hi all,
I have problem with my UDF. I am modelling a problem where apart from continuity and momentum, I have to solve energy, species transport and one UDS equation (for the volume fraction of Nano particle). The properties of nano fluid are calculated through UDF which depends on (UDS)Volume fraction of nano particle. The energy, species transport and UDS equations have Source term(in red color in attached Image) having terms like properties which are function of variable and other variable are being solve. Some part of the UDF code is written below it is giving parse error for the line
C_UDSI(c,t,2)= dtc * (C_YI_G(c,t,0)[0]);
C_UDSI(c,t,3)= dtc * (C_YI_G(c,t,0)[1]);

c_source= dct*(C_UDSI_G(c,t,4)[0] + C_UDSI_G(c,t,5)[1]);
while interpreting.I know that something is wrong with udf. (to calculate laplace of C and T). Also I do not have much idea about how to define unsteady term phi (Volume Fraction) instead of (phi * density) or User defined memory allocation. I don't know how exactly do it
I will be grateful for your help.

AlexanderZ will become famous soon enough
first of all compile your UDF instead of interpret,

next
Code:
DEFINE_ADJUST(adjust_UDS,domain)
{
Thread *t; 
cell_t c; 
thread_loop_c (t,domain) 
{ 
begin_c_loop (c,t)
{ 
C_UDSI(c,t,0) = C_VOF(c,t);
}
end_c_loop (c,t)
}
}
you have error here
Code:
C_UDSI(c,t,2)= dtc * (C_YI_G(c,t,0)[0]);
C_UDSI(c,t,3)= dtc * (C_YI_G(c,t,0)[1]);
because dtc is not defined.

probably, code has other problems, compile it and show log

best regards

Thank you Sir,
I have implemented the suggestion given by you. After compiling the code I am getting error message like..

Also i need some insight for the part..

C_UDSI(c,t,3) = dtc * (C_YI_G(c,t,0)[1]);
term3 = (C_UDSI_G(c,t,2)[0]);
term4 = (C_UDSI_G(c,t,3)[1]);

and

C_UDSI(c,t,4)= C_T_G(c,t)[0];
C_UDSI(c,t,5)= C_T_G(c,t)[1];
con_source= dct*(C_UDSI_G(c,t,4)[0] + C_UDSI_G(c,t,5)[1]);
Is this the right way to do the same??

I have read udf manuals and other related threads on this forum, but still unable to get rid of this problem.

Code:
DEFINE_SOURCE(con_source,c,t,dS,eqn)
{
real con_source;
change here name of function or variable.

Code:
C_UDSI(c,t,2) = dtc * (C_YI_G(c,t,0)[0]);
C_UDSI(c,t,3) = dtc * (C_YI_G(c,t,0)[1]);
there is some problem here, I'm not sure what is the problem, try to define dtc in other way -> don't use #define, but use real dtc=0.000001

All other parts seems correct and compiler didnt show other errors.
By the way - it is very very bad, when you have space in folder names.

IT is better if your source file is located in working folder, the same with fluent case file, which you are using

I don't go deep into your code, don't check if it is correct in terms of equations.
I assume you know, what you are doing. So I'm trying to help you with syntax

best regards

Dear Sir,
I have attached my udf and error that i am getting. The error comes before the first iteration.There is no problem with Interpretation of udf. There is no problem with initialization (and patching the domain ). I have also set the (rpsetvar 'species/save-gradients? #t). I think the problem is related with parallel processing or might be related with Environment Variable. Kindly guide me to find the problem and to do the same.

hi..
This is the mass diffusivity in Species Transport equation. Should it be defined by Define Property ?

no

the answer is: this is an error, which was clearly reported in YOUR log file
read your logs

should be
Code:
DEFINE_DIFFUSIVITY(nf_diffusivity, c, t, i)

Hi,I have some question with your code of the second derivative of the Temperature:
C_UDSI(c,t,5) = C_T_G(c,t)[0];
C_UDSI(c,t,6) = C_T_G(c,t)[1];
concentration_source = density_nf * d_soret * ((C_UDSI_G(c,t,5)[0]) + (C_UDSI_G(c,t,6)[1]));

Is that right to do so?

Hello everyone...
The modified code has been successfully compiled and initialised. But during iteration, following message shows and iteration does not start:

Node 0: Process 5584: Received signal SIGSEGV

MPI application rank 0 exited before MPI_Finalise () with status 2

The f1 process could not be started.


Please help in rectifying it.
