GGI + postCalc

Dear Foam users and developers,
i just wanted to have your opinion on what i consider as a possible bug concerning postprocessing for a GGI simulation: if i compute any quantity using postcalc (like Lambda2 or Q) for more than one time step, then i get unphysical values at the GGI frontiers in the visualization of those quantities. I'm trying now with an #include "createMesh.H" before each call of the calc function in postCalc.H, and it seems to solve the problem. Is this the correct way to do that? |

I get large discontinuities but not non-physical values...I only ever calculated vorticity though...

Hello,
Can you reproduce the problem with either one of the actual OpenFOAM 1.5-dev tutorials, or using one of the Turbomachinery test cases suite? Contributing a new test case is ok too. See here: http://www.extend-project.de/project...m-test-harness That way, we could add a new GGI specific test to the test harness. http://openfoam-extend.sourceforge.net/CDash/index.php Martin |

Hi Antoine and Pavan,
to avoid confusion for all OpenFOAMŽers allow me a bit housekeeping... AFAIK, GGI has been developed within the OpenFOAM-Extend Project for OpenFOAMŽ-dev. Details can be found in the Presentation at the Workshop in Montreal or the Presentation at the OSCIC - both given by Martin and Hrvoje in 2008. As this forum section concerns the core of OpenFOAMŽ as it is released by OpenCFDŽ Limited and as OpenFOAMŽ-Extend (among other features and functionalities) provides a own bug tracker MantisBT, all bug reports concerning OpenFOAMŽ-dev (soon OpenFOAMŽ-ext) specific features might be better placed here: http://www.extend-project.de/project...nd-bug-tracker best,

Hello all,
@Holger: since there is no specific forum until now for openfoam-extend (the forum on the openfoam-extend website points to this cfd-online forum), where can we then discuss about things, before being sure we're dealing with bugs? Additionally, at the time i started this thread, there was neither the brandnew openfoam-extend website, nor the Mantis bug tracking... Shall i now report that problem there? |

Hi,
thanks for the feedback. @ discussions of OF-Extend features (or problems related to them): Basically there are two possibilities IMO (and it was just meant to keep things sorted). You could either start a discussion with the special interest group closest to your problem (http://www.extend-project.de/user-gr...turbomachinery) or start a new thread within this forum. @ time of thread start: Sorry, didn't see that. P.S.: Please write me a mail / message or start a discussion in a more common forum part to talk further... I really think, this is the wrong place. best,
