Kindly check the UDF for ice-particle melting in ice-slurry as given below.

I have listed the errors I am getting just below the UDF.

#include "udf.h"

#define ds = 0.0001;
#define Latent_Heat = 21000;
#define alphas = 0.1;
#define ds = 0.0001;
#define v = 1.25;
#define lambdal = 0.5034;
#define mus = 1.72 * 10 ^-5;
#define mul = 0.70354;
#define rhos = 917;
#define Cpl = 4260;
#define latent_heat = 332400;

DEFINE_MASS_TRANSFER(mastra, cell, thread,from_index, from_species_index, to_index, to_species_index)
{

real hsl, Pr, hv, Res1, Res2, Res, mass;

Thread *sol, *liq;
liq = THREAD_SUB_THREAD(thread, from_index);
sol = THREAD_SUB_THREAD(thread, to_index);

Res = ((rhos*C_U(cell, liq)*ds / mus) - (rhos*C_U(cell, sol)*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(cell, liq) - C_T(cell, sol)) / Latent_Heat));

return mass;
}


Error: F:\\devshi\\pipe\\pipe_files\\dp0\\FFF\\Fluent\\ma stra.c: line 24: parse error.
Error: F:\\devshi\\pipe\\pipe_files\\dp0\\FFF\\Fluent\\ma stra.c: line 24: invalid type for pointer dereference: float.


Line 24 is: Res = ((rhos*C_U(cell, liq)*ds / mus) - (rhos*C_U(cell, sol)*ds / mus));

Kindly help to solve these errors.

I think you should write mus=1.72e-5

[devshi]

That still not having any effect on errors.

[Boh]

removing the equals in the #define ?
