| Summary | 0002535: postProcess utility doesn't work for multiregion cases | ||||
| Description | Following steps at chapters 6.2.2, 6.2.3, 6.2.4, 6.3.1, for postProcessing or sampling data, during solver execution (e.g. chtMutiRegionSimpleFoam) gives this warning, tested on multiRegionHeaterRadiation tutorial: --> FOAM Warning : From function bool Foam::functionObjectList::read() in file db/functionObjects/functionObjectList/functionObjectList.C at line 671 Caught FatalError --> FOAM FATAL ERROR: request for objectRegistry region0 from objectRegistry multiRegionHeaterRadiation failed available objects of type objectRegistry are 5 ( bottomAir rightSolid heater topAir leftSolid ) | ||||
| Steps To Reproduce | at multiRegionHeaterRadiation folder tutorial: >> cp $FOAM_ETC/caseDicts/postProcessing/flowRate/flowRatePatch system edit control Dict by adding functions { #includeFunc flowRatePatch } edit flowRatePatch and typing maxX as patchName run ./Allrun | ||||
| Additional Information | no folder postProcessing created | ||||
| Tags | chtMultiregionFoam, Post-processing | ||||

Note: when editing "system/flowRatePatch", also add the region, e.g.: region bottomAir; Nonetheless, this does not solve the problem right now, but does help isolate the issue and how to fix it, i.e. possibly load only the relevant regions and other regions are loaded only if explicitly requested? |

Regarding the original report, a workaround to this issue has been documented at the following forum post: https://www.cfd-online.com/Forums/openfoam-post-processing/187129-postprocess-run-time-data-processing-multiregion-case.html#post647272 - because this was originally asked there. The workaround is to use "chtMutiRegionSimpleFoam -postProcess" and properly configure the "functions" entry, e.g.: functions { flowRatePatch { name maxX; region topAir; #includeEtc "caseDicts/postProcessing/flowRate/flowRatePatch.cfg" } } ------------------------- Now, going back to the issue with the "postProcess" utility..... wait, this is already solved, at least since OpenFOAM 4.1. If I use the following command: postProcess -func flowRatePatch(name=maxX) -region topAir as listed in the first post on the forum thread, it works just fine in OpenFOAM 4.1 and 4.x, but fails in OpenFOAM 4.0. This was already fixed in commit 168b29e2cfc8062867ed30928d824188e0858630: https://github.com/OpenFOAM/OpenFOAM-4.x/commit/168b29e2cfc8062867ed30928d824188e0858630 This reported issue was due to the original reported using the port of OpenFOAM 4.x in blueCFD-Core 2016-1 that is missing this feature. I'm closing this issue as already fixed in OpenFOAM 4.x. |
