Composite Optimization with solid

Hi,

I would like to know if there is a tutorial available for Composite Optimization with solid elements? In the 'Skateboard' tutorial, it is mentioned that 'In case of solids one has to generate each ply as a solid' Which sounds very simple to me. But It doesn't work so far.

If there is no tutorial availabe, here is what I've done:

- Discrete one ply geometrie with CQuad4. Then I turned the 2D Mesh into CHEXA by drag 2D elements along an axis. I chose this method, because I wanted to create a periodic mesh with the 2D Elements for the other plies. So that I get the same mesh for each ply

- next I created sets for each ply by selecting all ply elements

- then I did ply defintion with the thickness of the solids for each ply and did laminate definition

- then I chose PCOMPP Card Image ( as it is mentioned in several composite tutorials)

- and I did Analysis.

 

The errors I get are: 'ERROR 14: Missing property #    2 referenced by   CHEXA #...........' with lots of elements. This is propably due to the PCOMPP Card. But I have no idea how to fix this and do all 3 phases of the composite optimization.

With a PSOLID Card it is possible to do free size optimization with a defined Laminate?

 

please can you help? Thank you in advance.

    Hi Martin,

     

    For Solid elements PCOMPP is not a compatible property. You have to use PSOLID with MAT9 or MAT9ORT. 

     

    Unfortunately there is no tutorial available which demonstrates optimization of solid element model with composite material.

     

    But we will try our best to help you out with your model :)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
