Transfer Line Load to a Shell

Hi, I am trying to transfer a line load to a shell element without having the line element influence my results. For instance, I can’t optimize my shell cross-section for displacements as they include my line element. Any way I could implement a line load and disregard the beam element in the analysis?

Thank you,

Mathieu

Dear Mathieu,
you could try the following: use short truss elements (beams with ‘Bending’ = false), and integrate them into your shell mesh using Karamba3D’s ‘MeshBreps’-component. Their cross sections need to be very small, so that they do not influence the response of the shell. Then place a line-load on the truss elements. This should lead to nodal loads on the shell elements which are equivalent to a line-load.
Best,
Clemens
