[JA_95]

Hi everyone, I am new to this forum and quite unexperienced with Fluent as well. I know that this question has already been answered but I couldn't really solve my issues.

From a RTD analysis I know that in a tubular reactor there are dead zones. I would like to take a contour of residence time inside the reactor in order to know where the dead zones are, so I would need to create a uds for mean residence time.. I already found a code here but when I run the simulation the uds is always equal to zero. Anyone can help? Thank you very much in advance

[AlexanderZ]

you don't need UDF to get mean values
there is an option "data sampling for time statistics", you may use it
solution -> run calculation -> options

but if you are telling us, that your UDF doesn't work, you should put it here with detailed description of your model and problems, with console output and so on

[JA_95]

Alexander, thank you very much for your answer, but in the sampling options I can't see the residence time, I think that I have to compile a UDF function.
I post here what I previously found

/*========================*/
#include "udf.h"
/*
* UDF to compute fluid residence time
*
* This UDF requires at least 1 UDS to be defined
* At inlet, define UDS (value) = 0
* UDS will have units of time and represent approximate residence time
* of fluid in domain
*
* Diffusivity of scalar should be small to reduce diffusion i.e. 1E-5
* However, for turbulent flow with recirculating regions, it is more appropriate
* to hook the function rtd_diff to the UDS diffusivity in the
* materials panel
*/


DEFINE_SOURCE(rt_source,c,t,dS,eqn)
{
real source = C_R(c,t);
dS[eqn] = 0.0;
return source;
}

/*
* in the function below, the turbulent schmidt number has been
* set to 1.0 in accordance with the references mentioned above
* and the fluid molecular diffusivity has been set to 1.0e-5 m2/s
*
* these values can be changed on an as-needed basis, for instance in
* Airpak mean age of air calculations, a value of 2.88e-5 is used



* for the molecular diffusivity and a value of 0.7 is used for the
* turbulent Schmidt number
*/
DEFINE_DIFFUSIVITY(rtd_diff, c, t, i)
{
return C_R(c,t)*1.0e-09+C_MU_EFF(c,t)/1.0;
}

What I do is:
1) Compile the udf function
2) setting a UDS
3)setting the boundaries condition (0 at the inlet)

Then I run a transient simulation but the residence time is always equal to zero and never increases.
I hope to have explained my problem properly, thank you

[AlexanderZ]

did you apply UDS source in Fluent GUI to the fluid zone?
go to zone -> select fluid -> sources -> uds-0 -> select your UDF source

Hello Alexander
I have a problem after exporting UDF output to a text file. I am running simulation on a cluster and it runs well. I basically have 2 issues:
a)The value of UDS appears to be zero in the console for all the iterations. UDS is for the concentration of species which are emitted from a cell zone. Please note that the source is specifies in GUI and not the UDF. A snippet of my code is as follows:

DEFINE_ON_DEMAND(pch_udf)
{
FILE* fp_pch;
fp_pch = fopen("PCH.txt", "a");
Thread *t,*to, ;
face_t f;
cell_t co;
Domain *d;
d = Get_Domain(1);

real A[ND_ND];
real x[ND_ND];

real PCH_turb_roof=0;




//loop for turbulent component of PCH(Roof)
thread_loop_f(t, d)
{
begin_f_loop(f,t)
{
F_CENTROID(x, f, t);
if (x[0] >= 108 && x[0] <= 126 && x[1] == 18 && x[2] >= 90 && x[2] <= 126 )
{
F_AREA(A,f,t);
co = F_C0(f, t);
to = THREAD_T0(t);
real integrand;
real conc_grad_roof;
real mu_t_roof = C_MU_T(co,to);
C_UDSI(co,to,0)= C_YI(co,to,0) * RHO_1;
conc_grad_roof=(C_UDSI_G(co,to,0)[1]);
integrand = (mu_t_roof /0.7)*conc_grad_roof;
PCH_turb_roof -= integrand*NV_MAG(A);
}
}

end_f_loop(f,t)
}
fprintf(fp_pch, "PCH_turb_roof %g\n",PCH_turb_roof);
}

b) After complete simulations, the parameters defined under execute on demand are 0 for some iterations and non zero for some in the output text file. but it should be non-zero after every iteration as far as I understand. Please let me know if I am doing something wrong or interpreting them wrong. A snippet of the output file is as follows:

PCH_turb_roof 0
PCH_turb_side1 0
PCH_turb_side2 0
PCH_mean_roof 0
PCH_mean_side1 0
PCH_mean_side2 0

first of all
compile your code and fix errors

[anonymous96_]

Hello Alexander
Thankyou for the response. Code is compiled successfully and runs without any error. The only problem is it gives zero values for the parameters.
However I fixed it partially using PRF_GRSUM1 which was suggested by you in some other thread I came across and it works and gives desired output for other parameters.
But the only problem is the piece of code mentioned above. I have come to realize that the problem is with C_UDSI_G term because I am getting 0 for only those parameters which include C_UDSI_G. I am attaching the code again for your reference:

#include "udf.h"
#include "sg.h"
#include "mem.h"
#include "math.h"
#define RHO_1 1.29

DEFINE_ON_DEMAND(pch_udf)
{
    FILE* fp_pch;
	fp_pch = fopen("PCH.txt", "a");
	Thread *t,*to;
	face_t f;
	cell_t co;
	Domain *d;
	d = Get_Domain(1);   
											
	real A[ND_ND]; 
	real x[ND_ND];
               
    real PCH_turb_roof=0;
thread_loop_f(t, d)
	{
	    begin_f_loop(f,t)
		    {
		        F_CENTROID(x, f, t);
				if (x[0] >= 108  && x[0] <=  126 &&  x[1] == 18 && x[2] >= 90  && x[2] <= 126 )
				{
                    F_AREA(A,f,t);
					co = F_C0(f, t);              
					to = THREAD_T0(t);      
					real integrand;
					real conc_grad_roof;
					real mu_t_roof = C_MU_T(co,to);        
					C_UDSI(co,to,0)= C_YI(co,to,0) * RHO_1;   
					conc_grad_roof=(C_UDSI_G(co,to,0)[1]);       

					integrand = (mu_t_roof /0.7)*conc_grad_roof;     
					PCH_turb_roof -= integrand*NV_MAG(A);            
                }
            }
                          
        end_f_loop(f,t)
	}
}

It is surprising because I am working on a cluster and the code compiles successfully without any error and even runs properly. I have tried the same on GUI and it runs properly even there. Below is the output given by cluster.
