Hi,
I'd like to study what happens in a convergent-divergent tube. So I used the solver "rhoSonicFoam". But, when I run the case, it stops and in the shell these words are shown:

--> FOAM FATAL ERROR :
request for surfaceScalarField phi from objectRegistry region0 failed
available objects of type surfaceScalarField are

4
(
weightingFactors
limiter
differenceFactors_
phiv
)


From function objectRegistry::lookupObject<type>(const word&) const
in file /home/dm2/henry/OpenFOAM/OpenFOAM-1.3/src/OpenFOAM/lnInclude/objectRegistryTempl ates.C at line 122.

I suppose that I didn't define one variable, but I don't really understand what does it mean.
Someone could help me, please?

Best regards,

Gabriele

Hello,

I also see the same messages when running rhoSonicFoam but only when doing any "freestream-type" inlet/outlet type boundary conditions. If the boundaries are all fixed, rhoSonicFoam runs fine.

Hope this helps,
Mark

Hi,

thanks for your answer.
But I have the same problem also when I use the other types of boundary conditions at the inlet and at the outlet. In particular, I have a convergent-divergent tube: so I'd like to impose the pressure both at the inlet and at the outlet. So I use the "pressureInlet" and "pressureOutlet" conditions respectively, but FoamX gives always the same error messages.
I don't know why.
Thanks for your patience.

Hi Gabriele,
I know it's been a long time since you had this problem, but I am wondering if you managed to solve this matter (as I'm almost in the same situation), how did you do?

Best Regards
