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!

    Hi,

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

    Sure! here is a screenshot of the 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.

    Thank you for your help.

    The model was extracted from AVIZO and only includes 3D elements without geometry. Should I start by creating 2D faces and then create 2D surfaces?

    Furthermore, how could I make sure the surfaces are closed volume?

    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.
