i am new to open foam but keep getting this error can someone help me with this

Hi,

I couldn't try at the moment but can you check that the topology of block is correct by defining a single hex block at a time, commenting other lines. Also, comments all boundary lines and check one at face at a time. Probably you can find clue to issue.

To check blocks are correct, try 'paraFoam -block'.

If possible please share the geometry as images you want to mesh. It will help people to give some ideas (otherwise it may not be feasible for everyone to try out, i hope you understand)

Thanks
