When I tried to interpret the following code, i got a message error 'line 6: parse error.'

#include "udf.h"

#define Cd 0.2 /* usually between 0.1 - 0.3 ; lambda = Cd * LAD */ 
#define LAD 2.0

real A1t = 1.0; /* Betap */
real A2t = 5.1; /* Betad */
real A3t = 0.9; /* closure constant cepsilon4 */ 
real A4t = 0.9; /* closure constant cepsilon5 */

DEFINE_SOURCE(xmom_source,c,t,dS,eqn)
{
real x[ND_ND]; 
real source;
real U = C_U(c,t);
real V = C_V(c,t);
real W = C_W(c,t);
real VEL = sqrt(C_U(c,t)*C_U(c,t)+C_V(c,t)*C_V(c,t)+C_W(c,t)*C_W(c,t)); 
real k = C_K(c,t);
real e = C_D(c,t);
real rho = C_R(c,t);
C_CENTROID(x,c,t);

source = -Cd*LAD*rho*VEL*U;
dS[eqn] = -Cd*LAD*rho*(U*U/VEL + VEL);
return sour

At a glance, you have not closed the square bracket

[Rob]

There's also a ? symbol in line 1: check for white space characters too.

[aitor.amatriain]

And "sour" should be "source" in the last line

[Ulfah]

Sorry this is the real code
#include "udf.h"┬Ø




#define Cd 0.2 /* usually between 0.1 - 0.3 ; lambda = Cd * LAD */

#define LAD 2.0




real A1t = 1.0; /* Betap */

real A2t = 5.1; /* Betad */

real A3t = 0.9; /* closure constant cepsilon4 */

real A4t = 0.9; /* closure constant cepsilon5 */




DEFINE_SOURCE(xmom_source,c,t,dS,eqn)

{

real x[ND_ND];

real source;

real U = C_U(c,t);

real V = C_V(c,t);

real W = C_W(c,t);

real VEL = sqrt(C_U(c,t)*C_U(c,t)+C_V(c,t)*C_V(c,t)+C_W(c,t)*C_W(c,t));

real k = C_K(c,t);

real e = C_D(c,t);

real rho = C_R(c,t);

C_CENTROID(x,c,t);




source = -Cd*LAD*rho*VEL*U;

dS[eqn] = -Cd*LAD*rho*(U*U/VEL + VEL);

return source;

}

Assuming the white space character isn't present, check if Cd is used elsewhere in the code: avoid 1-2 letter variables as we may use them elsewhere. A parse error warning is typically triggered on the line after the mistake, or rather the next line with text as the code found a fault but didn't know it was a fault until the next bit of code comes along.

Thank you for your help. I rewrote the code and I believe there was a white space character. I tried to interpret the new code and there seems to be no error occurred. However, I am confused with the message on the console which can be seen in the picture I attached below. What does this message indicate?

[Rob]

It's the result of the interpreter running through all of your commands. If it doesn't give an error or lots of warnings you can generally ignore it: it may mean something but no one I know has ever bothered trying to figure it out.
