After I run the mesh on my 14 stories building, there was no error on the mesh.
Unfortunately, when I asked to run the RC design, Graitec was unable to do it, stating that node 4494 RX and 5480TZ are unstable.
This has do with the transfer beams on 1st level for sure.
What shall I do? How can I meet these nodes and make them stable?
Thanks in advance
