You should define the linear release for only one panel (along the edge that is common for two panels).

Is it the same as for three edges?

I also get an error that ses "it is necessarry to divide tapered bar to valcilation elements for non -linear analysis"

How may i find where the elemnts are and how to remove them?

My understanding it that the actual warning is in fact that it is recommended divide (not remove) the bars of variable height for better precision of the results.

Just select these bars using their section names as the selection filter.

In the model you sent I can't see any such warning so my answer was the general one. As far as I can see you haven't installed SP3 for Robot 2013. I recommend you do so. The link is inserted below:
