Pieter is on a distinguished road
I'm relatively new to OF.

I'm trying to modify the rhoSimpleFoam tutorial for a simple own mesh created with snappyHexMesh.
After 7 timesteps I'm getting the following error.
Code:
Time = 0.07

GAMG:  Solving for Ux, Initial residual = 0.70316, Final residual = 0.0122983, No Iterations 1
GAMG:  Solving for Uy, Initial residual = 0.740811, Final residual = 0.0162203, No Iterations 1
GAMG:  Solving for Uz, Initial residual = 0.847864, Final residual = 0.00205627, No Iterations 1
GAMG:  Solving for e, Initial residual = 1, Final residual = 0.0364624, No Iterations 2

Floating point exception (core dumped)
~/OpenFOAM/ubuntu-4.0/run/elbow(610) paraFoam
Created temporary 'elbow.OpenFOAM'
Does anyone have an idea what I'm doing wrong

This is my physical properties file
Code:
thermoType
{
    type            hePsiThermo;
    mixture         pureMixture;
    transport       sutherland;
    thermo          hConst;
    equationOfState perfectGas;
    specie          specie;
    energy          sensibleInternalEnergy;
}

mixture
{
    specie
    {
        nMoles      1;
        molWeight   28.9;
    }
    thermodynamics
    {
        Cp          1007;
        Hf          0;
    }
    transport
    {
        As          1.4792e-06;
        Ts          116;
    }
}
I saw other post that floating piont errors might be caused by mesh errors. But my checkmesh is not giving any errors

Thanks in advance!
