Hello!

I want to extract and visualize internal connection forces on CLT panels, modelled as cross laminated timber elements, not orthotropic shells. It seems however that this module is not implemented yet in the FEMDesign API. Deconstructing the panel gives me the error message “1. Solution exception:Panel has more than 1 internal panel. Panel analytical model is not of type continuous”. Is there a workaround or do I need to wait for it to be implemented? 😄

Hi @annastig 👋

Welcome to the community!

Can you please send me a file to reproduce the issue?  
We might be able to find a work-around if urgent 🙂

Thank you Marco and thanks for the quick reply 🙂

I realized that it is possible to extract the results from the line connections of the internal panels still, just not possible to extract the actual panel. I’ll include a photo and a FEM file, but not urgent 🙂

Error message:

1. Solution exception:Panel has more than 1 internal panel. Panel analytical model is not of type continuous.
