| Summary | 0003762: XiEngineFoam crashes with adjustTimeStep yes | ||||
| Description | XiEngineFoam crashes with adjustTimeStep set to yes. Using dynamicCode for coded setDeltaT at line 57 in "/home/clemens/OpenFOAM/clemens-9/run/kivaTest/system/controlDict/functions/setDeltaT" Courant Number mean: 0 max: 0 deltaT = 0 Crank angle = -180 CA-deg deltaZ = 0 #0 Foam::error::printStack(Foam::Ostream&) at ??:? #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::fvMesh::movePoints(Foam::Field<Foam::Vector<double> > const&) at ??:? #4 Foam::layeredEngineMesh::move() at ??:? #5 ? in "/home/clemens/local/OpenFOAM-9/platforms/linux64GccDPInt32Opt/bin/XiEngineFoam" #6 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #7 ? in "/home/clemens/local/OpenFOAM-9/platforms/linux64GccDPInt32Opt/bin/XiEngineFoam" If I add the following Info output to setDeltaT.H if (adjustTimeStep) { scalar maxDeltaTFact = maxCo/(CoNum + small); scalar deltaTFact = min(min(maxDeltaTFact, 1.0 + 0.1*maxDeltaTFact), 1.2); Info<< "maxDeltaTFact " << maxDeltaTFact << endl; Info<< "deltaTFact " << deltaTFact << endl; Info<< "deltaTValue() " << runTime.deltaTValue() << endl; Info<< "maxDeltaT " << maxDeltaT << endl; runTime.setDeltaT ( min ( deltaTFact*runTime.deltaTValue(), maxDeltaT ) ); Info<< "deltaT = " << runTime.deltaTValue() << endl; } I get the following output: Using dynamicCode for coded setDeltaT at line 57 in "/home/clemens/OpenFOAM/clemens-9/run/kivaTest/system/controlDict/functions/setDeltaT" Courant Number mean: 0 max: 0 maxDeltaTFact 9.0072e+14 deltaTFact 1.2 deltaTValue() 2.77778e-05 maxDeltaT 0.000111111 deltaT = 0 Crank angle = -180 CA-deg deltaZ = 0 #0 Foam::error::printStack(Foam::Ostream&) at ??:? #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 Foam::fvMesh::movePoints(Foam::Field<Foam::Vector<double> > const&) at ??:? #4 Foam::layeredEngineMesh::move() at ??:? #5 ? in "/home/clemens/local/OpenFOAM-9/platforms/linux64GccDPInt32Opt/bin/XiEngineFoam" #6 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #7 ? in "/home/clemens/local/OpenFOAM-9/platforms/linux64GccDPInt32Opt/bin/XiEngineFoam" Floating point exception So for some reason, setDeltaT sets it to zero unconditionally. | ||||
| Steps To Reproduce | Take the tutorial $FOAM_TUTORIALS/XiEngineFoam/kivaTest and set adjustTimeStep yes | ||||
| Additional Information | Fixed in -dev, is a backport possible? | ||||
| Tags | No tags attached. | ||||

Correction: adjustableRunTime has to be set too for this issue to trigger. The function adjustDeltaT() in OpenFOAM/db/Time.C seems to fail if user time is in CA |

Try OpenFOAM-dev |

I am unable to reproduce the problem in OpenFOAM-dev, so I believe it is already fixed. |

Yes, the re-write of the userTime framework has resolved this issue. I will apply the patch that I posted for -9 locally. Thanks for the quick reply. Then both 0003761 and this report can be closed. |
