| Summary | 0001964: potentialFoam fails when a limitTemperature function is included in fvOptions | ||||
| Description | When I try to initialize the velocity field with potentialFoam of a rhoSimpleFoam model that is using the limitTemperature function in fvOptions, potentialFoam stops running with an error (seen in the additional information section). When I remove the fvOptions file or the limitTemperature function, everything runs fine. | ||||
| Steps To Reproduce | Please find attached a modified squareBend OpenFOAM tutorial. I have added the necessary lines in fvSolution ect need to run potentialFoam. 1.) Run Allrun 2.) Check the log.potentialFoam file, you'll find the error 3.) Remove or rename the fvOptions file, remove log files 4.) Re-run Allrun 5.) Check the log.potentialFoam file, it finished successfully. | ||||
| Additional Information | Here is the error produced by potentialFoam with the limitTemperature function defined. --> FOAM FATAL ERROR: request for basicThermo thermophysicalProperties from objectRegistry region0 failed available objects of type basicThermo are 0() From function objectRegistry::lookupObject<Type>(const word&) const in file /apps/OpenFOAM/.builds/OF30/837527a/OpenFOAM-3.0.x/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 198.

You cannot run potentialFoam with fvOptions specified to manipulate the temperature as this field does not exist in potentialFoam. If you need fvOptions specified for potentialFoam you will need to use a different file to that used for rhoSimpleFoam or if they are not needed for potentialFoam simply remove or move the fvOptions file. |

Ok, I listed this as a bug because it's a regression from 2.4.x. In 2.4.x, potentialFoam read but seemed to ignore the temperature limits in fvOptions and ran properly (as it should, since it shouldn't care about temperature constraints). I expected the same behavior in 3.0.x. You are correct, I can simply remove the fvOptions, run potentialFoam, replace it, and run rhoSimpleFoam. But this seems like more of a hack that I now need to place into the workflow to go from initialization to solve. I'm ok with it, but is there a reason for this regression? |

I ran your case in OpenFOAM-dev exactly as provided and specified and potentialFoam runs without error or warning: /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: dev | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : dev-119708e40132 Exec : potentialFoam Date : Jan 07 2016 Time : 14:04:19 Host : "dm" PID : 9704 Case : /home/dm2/henry/OpenFOAM/henry-dev/run/Bugs/potentialFoam/squareBend_mod nProcs : 1 sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).

Ok... well, it fails in the latest version of 3.0.x with the error I indicated. So either there was a regression in the 3.0.x branch or there was a seperate commit to dev since the release of 3.0 that fixed it. I'd like this bug to be resolved in 3.0.x if possible. I don't have an in order dev build right now, so your help in determining which commit fixed or broke it would be helpful. I will work on getting an updated dev build working on my end. Thanks for your support! |

I have made some substantial changes to the instantiation of fvOptions on OpenFOAM-dev to support fvOptions in model libraries such as for turbulence. It would not be appropriate to make the same changes to OpenFOAM-3.0.x as they do not relate to bug fixes. However, fvOptions are not currently used in potentialFoam anyway so there is no need for them to be instantiated and I will remove them from potentialFoam in OpenFOAM-3.0.x which should resolve the problem you are having. |
