[Fusuo]

I want to release a certain gas at a certain point in the fluid domain, but I can't see species after simulation using my UDF. The UDF as follows.


#include "udf.h"

#define M 0.00000796
DEFINE_SOURCE(Pullation_1,c,t,dS,eqn)
{
real x[ND_ND];
real source;
C_CENTROID(x,c,t);

if(x[0]==-0.15&&x[1]==0&&x[2]==0.001)
{
source = M;
}
else
{
source = 0;
}

dS[eqn]=0;
return source;
}
