Hi everybody!
I have this very bothering issue with the C_VOLUME macro, as well as with the C_R(c,t). I'm using a one phase mixture model with water vapors and air and I would like to determine de partial pressure for water. For this I need to determine the volume for each cell. The issue is that every time I insert one of the following macros I receive the signal sigsegv error. Could you please help me determine the reason for this? I streamed down my code to this.

#include "udf.h"
#include "mem.h"

DEFINE_ON_DEMAND(mass)
{
Domain *d = Get_Domain(1);
Thread *t;
int ID = 5;

t = Lookup_Thread(d, ID);

cell_t c;
real vol;

begin_c_loop(c,t)
{
vol = C_VOLUME(c,t);
Message("%e\n", vol);
}
end_c_loop(c,t)
}

in code you've posted thread (t) is not defined

you may do following

#include "udf.h"

DEFINE_ON_DEMAND(mass)
{
Domain *d = Get_Domain(1);
Thread *t;
cell_t c;
real vol;
int zone_ID = 12;
t = Lookup_Thread(d,zone_ID);
begin_c_loop(c,t)
{
vol = C_VOLUME(c,t);
Message0("%e\n", vol);
}
end_c_loop(c,t)
}

however, this code is doing nothing but printing volume of each finite cell in zone 12

Hi! Thank you for your replay! I attach my code with the ID changed in accordance with my geometry. The issue is that I want it to show me all the volumes of the cells in ID 5, but it does not. I compile the file and then when I want to execute it I receive the signal sigsegv error. I do not know what else to do.

#include "udf.h"
#include "mem.h"

DEFINE_ON_DEMAND(mass)
{
Domain *d = Get_Domain(1);
Thread *t;
cell_t c;
real vol;
int zone_ID = 5;
t = Lookup_Thread(d,zone_ID);
begin_c_loop(c,t)
{
vol = C_VOLUME(c,t);
Message0("%e\n", vol);
}
end_c_loop(c,t)
}
