2injections DieselFoam
 
Hi, im trying to inject fuel with two different injectionpressures.
It looks something like this
{
injectorType commonRailInjector;

commonRailInjectorProps
{
position (0 0 0);
direction (0 0 -1);
diameter 110e-06;
mass 0.7e-06;
injectionPressure 115.0e+6;
temperature 1000;
nParcels 500;

X
(
1.0
);

massFlowRateProfile
(
(0.0000 0)
(0.0001 1.0)
(0.0002 0)

);

injectionPressureProfile
(
(0.0 1.0)
(0.0002 1.0)
);

}
injectorType commonRailInjector;

commonRailInjectorProps
{
position (0 0 0);
direction (0 0 -1);
diameter 110e-06;
mass 0.7e-06;
injectionPressure 200.0e+6;
temperature 1000;
nParcels 500;

X
(
1.0
);

massFlowRateProfile
(
(0.00300 0)
(0.00301 1.0)
(0.00302 0)

);

injectionPressureProfile
(
(0.00300 1.0)
(0.00302 1.0)
);

}
}
)
The problem is that nothing happens until the later injections. Any ideas?
Thx

I got another problem too

mpirun noticed that process rank 13 with PID 11535 on node mn150.mpi exited on signal 8 (Floating point exception).

Does it have to do with the injection pressure?
