Thank for your reply!

Joint2D element can be used in 3D model?
It is observed that there is 2D in name of the element, so that I just want to know whether the element can be used in 3D model? And there is warning in opensees code when Joint2D element is employed in 3D model as follows.

WARNING Joint2D::setDomain(): has incorrect space dimension
space dimension not supported by Joint2DWARNING Domain::addElement - In element 40
no Node 71 exists in the domain
WARNING could not add element to the domain
Joint2D element: 40

while executing
"element Joint2D 40 9 23 10 2 71 7 0"
(file "FEM_Elements.tcl" line 51)
invoked from within
"source FEM_Elements.tcl"

Hi,everybody!
I have OpenSees Command Language Manual for OpenSees version 1.7.3 but I want to download newest version.
Please help me,Thanks very much.

Hi, I encountered same problem and I has solved by closing OpenSEES window after OpenSEES finish to calculate. And you can try to do it.

There are three test, such as NormUnbalabce, NormDispIncr and EnergyIncr, how do I choose OpenSEES's test? And how do I decide appropriate tol?

My dear friend:
i used <-xml $filemame> command, and there are -xml metadata labelling each column of data in output file including P,Mz,My,T,Vy,Vz,T and I am sure that Mz is in local coordinate system, so I think other component is also in local.

Hi everyone :
I had found answer,they are P,Mz,My,T,Vy,Vz and T in local coordinate system.

Description：After I use command "recorder Element -file ele1.out -time -ele 1 section 1 force",there are eight components in result file. After removing the time column, there are 7 columns.
Question: What's means these seven columns？

Thanks！
Wish you good luck!

Hi everyone!
Prompt me "failed to get compatible element force & deformation for element: 1 (dw:<<0.348037, dw0:0.423057)". What mean is that ?

I want to use C# to develope Opensees, how can I to do it?
