Automesh

Altair Forum User

I had a pentagon-shaped shell to mesh. I first created 6 nodes :

N1 (0, 0, 0)

N2 (10, 0, 0)

N3 (-10, 0, 0)

N4 (10, 12, 0)

N5 (-10, 10, 0)

N6 (3, 14, 0)

When I automesh these 2 elements, HM creates a curve on the inclined edges (segment from N4 to N6, for example). How can I specify to keep the edges straight?

Thanks!

Maybe you should draw some lines between your points before meshing. This way your meshing will have some guides.

I don't understand what you are doing exactly.

If you are using the 'ruled' function and select N1-N3 and N4-6, then the surface becomes a curved edge on the top. If you are using the 'spline' function and select all 6 nodes, then the surface becomes straight edges.

If you are remesh the 2 elements by automesh, be sure that the feature and vertex angle are not to big (e.g. try 30). So the remesh keeps straight.

To @Arnaud_Divialle: I'm from germany and don't understand french, thats the reason to write english ;-) !!

Oops! I forgot something when I explained my problem! After creating the nodes, I created 2 elements with N1-N2-N4-N6 and N1-N3-N5-N6, and then I automeshed these 2 elements.

Anyways, both of your posts were a good solution to my problem. Merci Arnaud, Danke sch√∂n Mario!
