Done.
I reduced the mesh resolution from 1 m/pixels to 10 m/pixels and peaks are gone.
I assumed that any value better than 10 m/pixels as said in the manual was fine, but apparently that's not the case.
Anyhow I can live with a reduced mesh resolution, as long as I can finally cross the bridges.
Thank you very much your support. You really take care of your clients.
