Hi
I need some help about how to solve this kind of problem.This notification appear during the generate mesh process, when it's finish the number of nodes increase considerably.

Anyone know how to solve this?
Thank you in advance!

I am unsure what the issue here is; that warning is fine, it's just saying there are a lot of elements to display so it could take awhile to load them. You can click 'don't display' and they will still be in your mesh.

@aero_head But there is some way to solve this warning? Because once this warning shows up, it don't desappear anymore. And I would like to know where these elements are too, because it's not clear...maybe if i knew it..., i could solve...it's just a guess anyway...

"Solve" this by coarsening the mesh. Otherwise, read aero_head's Post again please. This is just a warning, that alot of elements are going to be displayed and that your machine might take some time to show them or performance is going to drop.

There is no such thing as "too many elements" for a solver, if you think thats a problem. As long as your processing resources are sufficient.

It's just a warning to prevent you from potentially having to wait for a very long time before the mesh is being displayed. Or even overwhelming your PC entirely.
Kind of like MS Excel asking you to confirm changes to graphs if they contain lots of data points, and might take a while to process.

There is not necessarily something wrong with the mesh you generated, at least if you intended to get that amount of elements. Just click "display" and see what happens.
Or did you ask because no matter what you click, the warning doesn't go away?

If you dont want to see the warning when exceeding 1M elements, you can change the threshold value. Go to Settings -> Display -> Warn if elements displayed

I understand that many elements were created, but i thought initially that this could be a problem.But it's not a problem then that's fine and thanks @AtoHM

@Flotus1 No, is just a warning that appear in some moment during is generating mesh and disappear when a click to display or not. Thanks for the help!
