OpenFOAM simulation keeps restarting at a certain time step

I am running a pimpleFoam simulation. But at a certain time step when it reaches a a convergence, it restarts from time 0 again, and not progressing.
I am attaching the controlDict and 0.p here. But do let me know if you need anything else to better understand what's going on. /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v2006 | | \\ / A nd | Website: www.openfoam.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; location "system"; object controlDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // //application icoFoam; application pimpleFoam; //startFrom latestTime; startFrom startTime; startTime 0; //stopAt nextWrite; stopAt endTime; endTime 15; deltaT 1e-4; //writeControl timeStep; writeControl adjustableRunTime; //writeInterval 100; writeInterval 0.01; purgeWrite 0; writeFormat ascii; writePrecision 6; writeCompression off; timeFormat general; timePrecision 6; runTimeModifiable true; //PIMPLE adjustTimeStep yes; maxCo 2; maxDeltaT 0.01; // ************************************************** *********************** // functions { } /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: v2006 | | \\ / A nd | Website: www.openfoam.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class volScalarField; object p; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { n1 { type totalPressure; p0 uniform 0; } n2 { type totalPressure; p0 uniform 0; } naso { type uniformTotalPressure; p0 { type sine; frequency 1/3; amplitude 50; scale -1; level 0; } } walls { type zeroGradient; } defaultFaces { type empty; } } // ************************************************** *********************** // p.s.

I just found out that if I do a scaling of the geometry by transformPoints "scale=(...)", then this is happening. Is it wrong to do scaling this way?
