| Summary | 0001581: Fatal IO error using TableFile type BC with pimpleFoam | ||||
| Description | I have two cases which are exactly same except for the geometry, one is cylinder and the other is a box. One runs without errors and the other crashes due to an IO error. I can confirm that there are no apparent differences between the two cases. I spent a lot of time to make sure. The issue is with the format of the table file A detailed explanation is given here with neat formatting which is not possible here. Check it out http://www.cfd-online.com/Forums/openfoam-solving/149213-time-varying-velocity-inlet-boundary-conditions-using-tablefile-h.html | ||||
| Steps To Reproduce | Here is the git repository to the case file https://github.com/pruthvi1991/OpenFOAM-bug-reporting/tree/master/TableFile_error Run the case named crashing case. This one crashes for me all the time Run the case named successful case. This case runs without issue. Use the Allrun.sh scripts to run a case. | ||||
| Additional Information | Make sure that you change the path to dataFile for topAndBottom, fixedInlet patches located in 0.org/include/topAndBottom,fixedInlet Here is the link to that file for one of the cases. https://github.com/pruthvi1991/OpenFOAM-bug-reporting/blob/master/TableFile_error/crashing_run/inertial_0.2Mach_NACA0012_1e-3_6procs/0.org/include/frontBackTopBottomPatches The box case takes a little while to mesh. | ||||

I think this error is being caused because of using the same datafile for two boundaries. Looks like its necessary to have a file for every boundary with a time varying velocity. I was able to fix the error using a file for each and every boundary. |

The first issue is what you've already stated here: http://www.cfd-online.com/Forums/openfoam-solving/149213-time-varying-velocity-inlet-boundary-conditions-using-tablefile-h.html#post538784 Namely that the file "src/OpenFOAM/primitives/functions/DataEntry/TableFile/TableFile.H" has a wrong description, because this: \verbatim ( 0.0 (1 2 3) 1.0 (4 5 6) ); \endverbatim is wrong and it should be: \verbatim ( (0.0 (1 2 3)) (1.0 (4 5 6)) ); \endverbatim I still need to check the second issue, namely if there is a problem with opening the same file twice. |

@pruthvi1991: The second problem, namely the original report, doesn't exist. You had included the same file for the boundary settings "topAndBottom" for both the "U" and "p" fields. Therefore, it was a user error, not a bug. Nonetheless, the description in the header file still needs to be updated, as indicated in the previous comment. |
