Hi,
I having some troubles using the fictitious shell components. I feed the component with the required information but the Construct model component does not read the shells as elements.
Any Idea why?
It seems that flexural stiffness have some constraint.
fictitious shell; Message: Can’t import this item, because bad flexural stiffness matrix! (xx * yy <= xy * xy)
Have a look at the “log” file within the “FEM-Design API” folder that the API creates for you.
I will solve the bug and raise an error

Always quick response, thanks @MarcoPelle
Where can I have a look at the log file?
@TommasoVidali
the “logfile.log” is usually located inside “FEM-Design API” folder that it is located where you have saved your .gh file

Hej @MarcoPelle, i am working together with @TommasoVidali on this project and just just wanted to ask if there is an development on this issue?
Ehy @ojhq !
The tool is working as expected but there is a limitation in the error handling that I still need to develop.
It looks like that you were using input that are not allowed my FEM-Design.
i.e.
Can’t import this item, because bad flexural stiffness matrix! (xx * yy <= xy * xy)
Did you encounter other issues?
It works now, we had some wrong input in the flexural stiffness definition.
