Hi guys
I have written a blockMesh file and the error continuously comes out: Code:
--> FOAM FATAL IO ERROR: "ill defined primitiveEntry starting at keyword 'boundary' on line 55 and ending at line 125" file: /home/francisco/Escritorio/horno/constant/polyMesh/blockMeshDict at line 125. From function primitiveEntry::readEntry(const dictionary&, Istream&) in file lnInclude/IOerror.C at line 132. FOAM exiting Can anyone help to have a look at the error here? Thanks a lot! Code:

Hi,
You probably had a stray invisible character somewhere in the text file. Delete blockMeshDict, make a new one and do a copy-paste from the above. blockMesh runs for me, but you still have problems with the mesh (not surprising): Code:
