UDF for mass transfer between phases in two phase ice-slurry pipe flow
 

I have wrote a UDF for melting of ice-particles in two-phase ice-slurry pipe flow

The code is as follows:

#include "udf.h"
/* UDF to define a simple mass transfer*/

DEFINE_MASS_TRANSFER(UFD, cell, thread, from_index, from_species_index, to_index, to_species_index)

{real mass;

real hsl = 1;
real pr=1;
real C_YI(c,t,1);
real ds = 0.0001;
read latent_heat = 21000
real alphas = 0.1;
real ds = 0.0001;
real v = 1.25;
real lambdal = 0.5034;
real mus=1.72*10^-5;
real mul=0.70354;
real rhos=917;
real cpl=4260;
real latent_heat=332400;

Res= rhos*|C_U(c,t,2)-C_U(c,t,3)|*ds/mus;

Pr=mul*Cpl/lambdal

hsl= (lambdal/ds)*(7+(10*alphas)+(5*alphas^2))*(1+0.7*(Res^0.2)* (Pr^1.3))

hv=6*alphas*hsl/ds;

mass= hv*((C_T(c,t,2)-C_T(c,t,3))/latent_heat);

return mass;
}


I am keep getting error that :

Error: The UDF library you are trying to load (C:\Users\Devshi\Downloads\pipe\pipe2_files\dp0\FF F\Fluent\libudf) is not compiled for 3d on the current platform (win64).

The system cannot find the file specified.


Kindly help

is it the first time that you compile an UDF?

Yes, this is my first time. Kindly advice

ok...then I had the same problem, for me it worked to disintall all visual c programs and install the Microsoft Visual Studio Express 2015 and then to add the path where "fluent.exe" and "runwb2.exe" to the "path" enviroment variable....then I rebooted the system and it worked...

Thank you for your kind help. I'll let you know about the progress soon.

Thanks again!

Also ensure you're correctly unloading and compiling the new UDF by following my compiling process for Fluent UDFs with an existing library loaded.
