Hi everyone,
I'm studying a spray without combustion. I need to set a injection pressure profile, but just after first iteration, I receive a error.

the Pinj table is:

(0.00000 0.00000)
(0.00010 6000000)
(0.00180 6000000)
(0.00190 0.00000)
(0.00500 0.00000)

the pressure in the chamber is 0.2MPa.

this is the error:

#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
#1 Foam::sigFpe::sigHandler(int) at ??:?
#2 ? in "/lib/x86_64-linux-gnu/libc.so.6"
#3 Foam::ConeNozzleInjection<Foam::KinematicCloud<Foa m::Cloud<Foam::SprayParcel<Foam::ReactingParcel<Fo am::ThermoParcel<Foam::KinematicParcel<Foam:arti cle> > > > > > >::setProperties(int, int, double, Foam::SprayParcel<Foam::ReactingParcel<Foam::Therm oParcel<Foam::KinematicParcel<Foam:article> > > >&) at ??:?
#4 ? at ??:?
#5 ? at ??:?
#6 ? at ??:?
#7 ? at ??:?
#8 ? at ??:?
#9 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6"
#10 ? at ??:?
Floating point exception (core dumped)
---------------------------------------------------------------------------------------

I think that the error is due to this formula:

U = sqrt(2*(Pinj - Pamb)/rho)

because (Pinj-Pamb) is < 0

so the question is, can I set a Pinj=0? because I have to set in the model this pressure profile, look at attached.

help me!
