Its Okey. You can get rid of this error by changing the analysis motor

hi,
I was not able to download the Opensees Source code from the opensees repository through SVN today.
how did you do it?
please help me.
thanks

hi
how can use "UniformRotationalExcitation" command in OpenSees?
there is no example for this command.
I thank you for help me

you can use rigidLink.
try this command

i see your model.
the model is not correct. some problem in your model.
if you see the node displacement , You will find

are you use opensees2.4.6?
this version of OpenSees in material hysteretic is not correct action

no need,
truss element no need to define geometric Transformaion.

its simple you must use element zerolenght to equal element. and if you want model shear story (like rigidDiaphragm in 3D ) you must use rigidLink -beam. ###################################################################################### material for element zerolenght : set Fy_S 1000000000000000...

correct, if your master node is "2", command : equalDOF 2 5 1 2 ,, if master node is "5" , command : equalDOF 5 2 1 2 no, internal force in rigid link is dosent exist. this element just made the "rigidDiaphragm" in 2D model. Example: (node 1)*-----------*(node 2) , ****...

1. rigidlink just need define base bay beam or truss action. its mean this element just "equal tow node" in 2D model. this element not have stiffnes or Real member.

2. if you assige pin connection, you need define this element for "slove" node.

send me the model

hi node 9, 10 , 11 , 12 is my roof Structure. node 1000 is my Central node for my rigidDiaphragm when i use mass like : mass 9 [expr 15066.*0.25] [expr 14066.*0.25] [expr 15000.*0.25] 1.e-9 1.e-9 1.e-9 mass 10 [expr 15066.*0.25] [expr 14066.*0.25] [expr 15000.*0.25] 1.e-9 1.e-9 1.e-9 mass 11 [expr 1...
