Dear Foamer,

I'm trying to use the interFoam to simulate the mixing of two fluids.
1. When running the blockMesh there is no errors.
2. After that for runing the setFields (no errors) : please do not forget to do the cp0/alph1.org 0/alpha1 before runing the setFields
3. runing interFoam : I think that there is some issues with the initialisation or may be the mesh, but I could not figure out what it is
exaclty : the error message is :

----------------------------

Create mesh for time = 0

PIMPLE: Operating solver in PISO mode
Selecting incompressible transport model Newtonian

Selecting turbulence model type laminar
Calculating field g.h
No finite volume options present
time step continuity errors : sum local = 1.47059e+292, global = 1.47059e+292, cumulative = 1.47059e+292

#0 Foam::error:rintStack(Foam::Ostream&) at ??:?
#1 Foam::sigFpe::sigHandler(int) at ??:?
#2 Uninterpreted:

---------------------------------------
As you can see the sum local is too high, I think taht in the beginig of calculation some dividing by zero occured
Honestly, I don't know how to fix it, do you have any ideas
it would be really appreciated !

Many thanks
