How can I create meshes of plate elements from nodes in HyperWorks release of version 2022.2?

Pasquale Cesarano

In HyperMesh Legacy I usually use Ruled panel under 2D Page to create mesh of 2D elements from nodes.

Due to fact that the option Ruled doesn’t available under 2D Page now, How can I do the same operations in HyperWorks release version 2022.2?

I tried to use the Ruled Ribbon under Geometry menu, as shown in the image below, but I don’t have the possibility to create elements from nodes (I can create only surface).

Thanks in advance,

 

Warm regards,

Pasquale

Hi Paulo,

thank you for your answer.

No, I'm not trying to control the elements density on the edges, I would like to create 2d mesh from temp node and to remesh them.

The figure below shows what I usually do in Hypemesh Legacy.

Best,

The new Ruled tool, on Geometry Ribbon, will only create a surface. You can then 2D mesh it and if you don't want to keep the surface, delete it.

If you want the mesh straight out of the Ruled tool, you can do as Hakan replied, changing the configuration of Geometry Creation.
The resultant mesh will not be great, but you can 2D mesh over it. And now, instead of having a surface and a mesh, you will have FE Geometry (which is a mesh that's enabled for all geometry tools, so It behaves as a geometry entity. That's why It's stored as a Geometry in the Components Browser):

If you change the geometry creation option to FE geometry in the Preferences section, elements will be created.

Hello, Pasquale.

If what you're trying to do is to control the elements density on the edges, I suggest using General 2D Mesh, with the Advanced Option to Link Opposite Edges Method, which will identify opposing edges and make them have the same density:

The meshing tool will then switch from "Create" to Density, where you're able to set how many elements you wish certain edge to have. Because the "Link Opposite Edges" was set to Automatic, this will happen:

I clicked on the yellow edge and the black ones are linked, so if I change the density of one of them, the others will follow.

Hope that helps!

Hi Hakan, 

thank you for your reply.

Do you know how to edit interactive the element created by using ruled function?

In Hypermesh Legacy there is this possibility after selected the nodes and clicked on create. 

 

Thanks,

Pasquale

Hi Paulo,

Thank you very much for your reply. Now, I understand the procedure. 

I have last question 

Why do I get different results when I use general 2D mesh tool if I choose I crete mesh selected surface instead elements?

I will try to explain better.

1) I used ruled tool to create FE Geometry: 

2) In order to improve/change the mesh, I use General 2D mesh by selecting surfaces create with rule tool. In this case I obtain the following results (the results is always FE GEometry):

3) If Instead I use I use General 2D mesh by selecting ELEMENTS create with rule tool. In this case I obtain mesh overlap:

Why does happen this? 

The preferences in meshing are shown below:

thanks for your kindly support.

Best regards,

Pasqule

Pasquale,

I tried recreating this unexpected behavior by using the same configurationd and similar workflow, but everything is working as It should. I created the surface using Ruled with Geometry creation set to FE Geometry.

Remesh by Surface Selection:

Remesh by Elements Selection:

Since you've been experimenting many configurations and tools, I suggest you close this test model and clean the temporary files generated by HyperWorks. This can be done by closing all HW instances and running a .bat file available in the Installation path:

C:\Program Files\Altair\2022.2\hwdesktop\utility\HWCleanup

Do this and retry the operations please.
