Hi everybody,

any body knows what is the meaning of this error:

Floating point exception

I'm solving natural convection with a modified viscoelasticFluidFoam solver.

Thank you

in the wiki I found this:

There is lots of interesting information in there. It shows the type of error (sigFpe which means a division by zero or any other operation causing an invalid floating point number) and who caused it (operator/ of an fvPatchField). Further down is the origin, kEpsilon::correct(), which obviously does some divisions. A good guess is that one of the patch fields of k or epsilon is 0.

but I check whole the code I have written before and I checked the boundary conditions. there isn't any divide by zero and also I didn't use kEpsilon.

I'm still struggling with this error . is here anybody knows the source of this error??!?

In your case Co seems to be decreasing during the simulation..

Hi Mostafa
i have same error when i modified interphasechangeFoam solver and add Temp Eq...
now,do you know how to solve this problem?
my error:
Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam211/platforms/linux64GccDPOpt/lib/libOpenFOAM.so"
plz help
regard

hi
please post the complete text of error.
your co number?

T N Q for reply
As i said,i modified interPhasechangfoam solver and just add Temp Eq (compile without problem) ,after that i want run a tutorial case(cavitating Bulet) after modified,but i have this error:

i'm very confused...now i just want runing a toturial case (interphasechangeFoam-cavitating Bulet) again,and same error for that! what Happen!!
