Thanks for your reply,
I took a good look at point 8216 and it seems fine.
I also resumed the mesh and restarted the simulation and I get a similar message, but with point 8086 (below). And looking at this point, it seems quite normal (see image with point of node 8086 in red).
Please find attached my mesh file boundary conditions file and harmonic file.
Thanks for your help.
