How to Convert 2D faces into solid
Hello,
I have a question about converting 2D faces that I've extracted from 3D elements into a solid. I've tried using the FE Geometry option under Topology to convert the elements, but I'm facing an issue. When I convert each of the three phases (colors) into a solid one by one, parts of the same phase are getting assigned different colors. For example, while converting the green phase, some parts unexpectedly turn red.
Could you please help me with a way to convert each of these phases into solids one by one without this problem?
Thank you!

- Created solid elements from 3D elements exported from AVIZO.
- Extracted 2D faces from these 3D elements.
- Generated solids again from the 2D faces.
- Created node set lists for all faces of the 3D model.
To create solids from elements, you must first generate surfaces from the FE model
Go To : 2D> Surfaces> From FE ( select all the elements) > create.
This will create the surfaces. Now Make sure this surface created has the closed Volume in order to generate the Solids .
To create Solids from Surfaces
Go to : 3D > Solids> Bounding> Create.
I hope this is helpful.
Yes you should start with Creating the faces for the 3D elements ,
Go to : Validate> Faces> Select the elements and create Faces.
Later you can create surfaces from the "from FE" tool, as I mentioned in the earlier chat.
The easiest way to check the weather the surfaces are closed volume is through
3D> Bounding tool > Find. If you just click "Find" Radio button on this tool, it will highlight the surfaces
if it makes a closed volume. This is one of the way to check and we have various ways too.

I believe that in the previous version (HyperMesh 2019), there was an option to select the four nodes of a face, allowing the software to restrict the degrees of freedom for the specified surface. However, I couldn’t find an option to select faces in the current version. Could you please help me with how to achieve this? Additionally, the Constraints feature remains inactive when I attempt to use it as shown in the above image.
Thank you!
Hello Prajval,
I am trying to export a list of solid elements along with their assigned nodes in the following format (as an example):
*ELEMENT_SOLID
$# eid pid n1 n2 n3 n4 n5 n6 n7 n8
1 2 2 32 5 4 4 4 4 4
2 2 2 29 32 28 28 28 28 28
3 2 4 32 31 28 28 28 28 28
4 2 2 4 1 28 28 28 28 28
5 2 2 28 32 4 4 4 4 4
Here’s what I’ve done so far:
However, when I exported the .k file to import it into LS-DYNA, the file did not include the required solid element list as shown above.
Could you please guide me on how to fix this issue and properly export the solid element list in the desired format?
I attached the file for your consideration.
Thanks

Hypermesh has various functions to deal with Geometry edges and create Volumes.
user can rely on 2d> Surface repair functonality or under Topology you can use > Split/Stitch or Quick edit function to close the edges .
To Create a solid use 3D> Solids> Bounding function.

Hi,
Could you share the model with us to have a look and suggest the best possible approach?
