Due to panel geometry or support conditions def. calc. may be incorrect

[Hallvard]

When doing calculations for reinforcement for walls I get this warning / error:

"Due to panel geometry or support conditions deflection calculation for panel __ may be incorrect"

It occors several of my walls. The walls are rectangular (no abnorm geometry), and they are supported by linear supports, pinned.

Can anyone tell me any typical reasons for this problem?

- Thanks

The walls...
In case of slab \ floor panels program finds columns or supports to establish initial points (surface) for calculating RC deflections.
In case of wall there are no such points so program finds the less displaced nodes to create such initial surface and displays warning as you mentioned.
