Hi guys,

Im using chtMultiRegionFoam with OpenFOAM 2.1.1 . My time step is very small. Its order is about 8e-8 . After simulation worked for 25ms, temperature stays almost same, it is not increasing. When i change co number little bit it works normally and temprature starts to increase. After work for 3-4ms it happens again. When i increase Co number again, it works normally and it happens again and again. Do you have any idea?

This is my fvsolution and fvschemes
ddtSchemes
{
default Euler;
}

gradSchemes
{
default Gauss linear;
}

divSchemes
{
default none;
}

laplacianSchemes
{
default none;
laplacian(K,T) Gauss linear limited 0.333;
}

interpolationSchemes
{
default linear;
}

snGradSchemes
{
default limited 0.333;
}

fluxRequired
{
default no;
}

fvsolution

solvers
{
