Define SPTs with numbers for each plate, e.g.: Spt No 11 x 0 0 0 Spt No 12 x 0 1 0 Spt No 13 x 2 1 0 Spt No 14 x 2 0 0 Spt No 21 x 2 0 0 $ Spts with explicitly different nr at same coordinate do not merge Spt No 22 x 2 1 0 Spt No 23 x 4 1 0 Spt No 24 x 4 0 0
Define SLNs with numbers for each plate, e.g.: Sln No 1112 Npa 11 12 Sln No 1213 Npa 12 13 Sln No 1314 Npa 13 14 Sln No 1411 Npa 14 11 Sln No 2122 Npa 21 22 $ Sln explicitly connected to different Spts → doesn’t merge Sln No 2223 Npa 22 23 Sln No 2324 Npa 23 24 Sln No 2421 Npa 24 21
Define SARs using the SLNs, e.g.: Sar No 10 SarB Type out NL 1112,1213,1314,1411 Sar No 20 SarB Type out NL 2122,2223,2324,2421
Add a constraint or spring between the adjacent lines, e.g.: Sln No -2122 $ - for altering an existing Sln SlnS RefT >Sln Ref 1314 Ca 1000 $ Coupling/spring to line
$ Some support conditions at the ends as well:
Spt No -11 Fix F $ Either pointsupport
Sln No -1112 Fix F $ Or linesupport

I’m working with sofimsHC indeed. Anyways, I adapted my workflow, and now it works fine.
I’ve stumbled upon the next problem however. How do I decide the rotational spring stiffness. The spring stiffness should be the same as the bending stiffness of the plate itself, i.e. EI [Nm²]. However when I look in the sofimshc manual, the unit should be kN/rad, which I don’t understand.
