Hi Foamers,

I am facing a problem which is ...
when I running my simulation, it will crash at different simulation time when I set different writeInterval value in controlDict file.

For example, the control dict below

/*--------------------------------*- C++ -*----------------------------------*\
| ========= | |
| \\ / F ield | OpenFOAM: The Open Source CFD Toolbox |
| \\ / O peration | Version: v1812 |
| \\ / A nd | Web: www.OpenFOAM.com |
| \\/ M anipulation | |
\*---------------------------------------------------------------------------*/
FoamFile
{
version 2.0;
format ascii;
class dictionary;
object controlDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

libs ("liboverset.so");

DebugSwitches
{
overset 0;
dynamicOversetFvMesh 0;
cellVolumeWeight 0;
}

application overInterDyMFoam ;

startFrom latestTime;

startTime 0.0;

stopAt endTime;

endTime 15;

deltaT 0.001;

writeControl adjustableRunTime;

writeInterval 0.5;

purgeWrite 0;

writeFormat ascii;

writePrecision 6;

writeCompression off;

timeFormat general;

timePrecision 6;

runTimeModifiable yes;

adjustTimeStep yes;

maxCo 1.5;
maxAlphaCo 2;
maxDeltaT 1;


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

With the configuration my case will simulate longer than the writeInterval value = 0.1,
and then crashed.

I don't know why the different output interval will cause different result???

Is because of the it will re-read the output and causing not continuous simulation?

Any idea will appreciated!!
