|0002168||OpenFOAM||Patch||public||2016-08-01 16:14||2016-08-01 17:07|
|Target Version||Fixed in Version||4.x|
|Summary||0002168: src/fvAgglomerationMethods/Allwmake still references unused Scotch environment|
|Description||From what I can figure out, the "scotchGamgAgglomeration" was something that was started back in 2013, but wasn't completed. Nonetheless, remnant references to it have been on this Allwmake file for sometime now and the previous change only removed the explicit reference to that library.|
Attached is the updated file "Allwmake" to replace "src/fvAgglomerationMethods/Allwmake" in 4.x, which removes the sourcing of the Scotch environment, which is not used, given that "scotchGamgAgglomeration" doesn't exist :(
The attached file is mostly applicable to OpenFOAM-dev, but the "targetType=libso" line (~5th line) isn't needed in OpenFOAM-dev.
|Tags||No tags attached.|
|Unfortunately the agglomeration method provided by scotch still doesn't work which is why we have not included the interface to it. We hope at some point in the future this part of scotch will be fixed and we will then release an interface to it. In the meantime I guess all references to the building of it can be removed.|
Many thanks for the details!
I did think that the agglomeration algorithm was meant to be mostly set-up on OpenFOAM's side and that Scotch only had to sort out the graphs based on the relation weights. This was why I did think that the code hadn't been completed due to the complexity of the preparation algorithm (i.e. not enough funding or time).
The other possibility would be to bring back in commented form the line for building "scotchGamgAgglomeration", but I can't find any public signs on there being any work being done on this from Scotch's development side, at least not under the name of "agglomeration".
|As far as I am aware the agglomeration functionality in scotch is not being developed at the moment, in fact it looks like scotch is now only being maintained. I hope that scotch development restarts at some point and the work on the agglomeration is completed/debugged.|
