belkadi is on a distinguished road
Dear Foamer,

I'm trying to use the interFoam to simulate the mixing of two fluids.
I've uploaded the test case:
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/ 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

deltaT = 3.15844e-298
Time = 3.15844e-298
MULES: Solving for alpha1
Phase-1 volume fraction = 0.939827 Min(alpha1) = -0.114728 Max(alpha1) = 1
MULES: Solving for alpha1
Phase-1 volume fraction = 0.938477 Min(alpha1) = -0.229443 Max(alpha1) = 1
#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
