Hi Foamers,

when i was working on a case using chtMultiRegionFoam, i found this error message while running blockMesh.

Hi Ahmed,

Without seeing more of the file, I can only assume that you're missing this part of the file:

Code:

Hi Bruno,

Hi
Please post complete blockMehDict.
Use dropbox to upload large file and to avoid long threads.
Generally we miss out braces and place the co-responding one correctly , and the compiler checks only for extra character i.e braces in this case.

Hi,
Could you please see the bold character below in your blockMeshDict.
"internal face" has to be one single word and not separated word ,which happens to be in your case so join them by using a underScore or something.
And same should be done for "outer face"
Hope this helps.
