This code is unrelated to your error (you don't include any files in
your .geo).
The message means that Gmsh could not open the output file for writing:
you might not have write pemissions in the directory, or the disk might
be full, ...?
I could mesh your geometry without problems on my laptop. (For
repetitive geometries like this you might want to use a function to
generate each block; and maybe generate the grid by extrusion.)
