Hi

1. What is the difference between elastic ground bars from the geometry>additional attributes menu and elastic linear support from the geometry supports menu?
2. If I have a raft with integrated beams, do I assign elastic supports to the raft and then additionaly assign elastic ground bar properties (or elastic linear support) to the beams?

1. The later can be applied to the edges of the panels only.

2. No, this will 'double' the elasticity along the beams.
