can you explain what is RBM?

first add ; in your Description text reform rigidLink beam 4 5; # connect node 3 to node 4 via a rigid link-beam # use ; # befor your Description text if didnt correct then: delete text: puts "ok 4" ########################## rigid link beam ################ rigidLink beam 4 5 # connect no...

hi, these is problem in my opensees text. i can not find out how to correct it. warning BandGenLinLapackSolver::solve <> -LAPACK routine returned 27 warning NewtonRaphson::solveCurrentSteph -the LinearSysOfEqn failed in solve <> static analysis::<> -the Algorithm failed at iteration: 0 with domain a...

may be
do not use rigid Diaphragm in 2d model
it works in 3d model
use equalldof for Rigid Diaphragm
: equalDOF 10 20 1:
why you use ridid link?
