CFD Online Discussion Forums - accessing current time

It is possible to access time using java or usercode (C, FORTRAN) The documentation how to compile and bind user code is actually pretty good. Read it and follow the instructions mentioned there.

The following files should do what you want, except that they are only updated while iterating. (Havent found a way to force an update yet)

Code:

//filename =  uclib.c

#include "uclib.h"

void physicaltime(Real*, int, Real*);

void 

uclib()

{

ucfunc(physicaltime, "VectorFieldFunction", "physicaltime");

ucarg(physicaltime, "Cell", "Temperature", sizeof (int));

}

Code:

//filename = physicaltime.c

#include "uclib.h"

#include <stdlib.h>

void physicaltime(Real (*result)[3], int size, Real *T) {

 

int i;

unsigned int t;

int seconds, minutes, hours;

t = time(NULL);

 

seconds = t % 60;

minutes = (t % 3600 - seconds) / 60;

hours = (t % 86400 - 60 * minutes - seconds) / 3600;

for (i = 0; i != size; ++i) {

result[i][0] = hours;

result[i][1] = minutes;

result[i][2] = seconds;

}

}

this gives you access to a vector field function called user physicaltime [hrs, min, sec].
