This will get more attention on the 3D simulation forum.
I found this on the first page in that forum:
Hello cowski1 !
Thanks for your answer but I have already seen this topic.
It's not answering to my question because I need to hide these element edges in the Simulation Navigator and not in the Post Porcessing Navigator (plot result)....
You can hide the entire mesh if you like. If this is not what you want, I suggest that you post your specific question to the appropriate simulation forum.
