Hello everyone

I want to mesh a thin plate in the x-y plane and apply cyclic/periodic boundary conditions for each of my internal fields. Then I would like to use a compressible solver dbnsFoam (p, T, U) to move a vortex. I am trying to reproduce the results in that paper: https://dl.acm.org/citation.cfm?id=3067565, section 7.5.

Here is my 'blockMeshDict'

Code:

and here is my error message

Code:
Creating block mesh from

Segmentation fault (core dumped)
I am using foam-extend-4.0 on Linux Mint 18.

Can you help me figure out what is wrong in this piece of code ?

Thanks
