what does this mean for the eigenvalue analysis?

[mokiao]

Can any one help me to understand what happened in my model?
I have used master node 3000 to put concentric mass for the rigid Diaphragm
When I run the eigenvalue analysis

the message comes:
SAWSMaterial unaxial material - Written by Paxti Uriz, Exponent 2009

what happened to the node 3000, why it is can not be recognized??

Thank you in advance!

Which nodal recorder do you have on node 3000?

node 3000 is a master node in the third floor rigid diaphragm. I recorder it like below for the eigenvalue analysis:
1000 2000 and 4000 are the master nodes for 1st, 2nd and 4th floor diaphragm.

for {set k 1} { $k<= 5 } { incr k} {
recorder Node -file [format "modes/mode%i.out" $k] -nodeRange 1000 2000 3000 4000 -dof 1 2 3 4 5 6 "eigen $k"
}

I did the same thing for 3000 node as 1000 and 2000 nodes, is there a problem in the third floor?

Thank you so much, Vesna!

Try this:

for {set k 1} { $k<= 5 } { incr k} {
recorder Node -file [format "modes/mode%i.out" $k] -node 1000 2000 3000 4000 -dof 1 2 3 4 5 6 "eigen $k"
}

If you use -nodeRange you need only 2 arguments $startNode & $endNode, but here you have used 4.

Thank you so much, Vesna, that is exactly the problem.

Would your please let me know why I encounter the followoing error when I run this commands?

set a {1 2}
recorder Node -file $direction/Reigenvector-Mode$ModeNumber-Node$NodeNumber-x.out -precision 10 -node 1 -dof $a "eigen 1 "


NodeRecorder::NodeRecorder - dataToStore 1 2not recognized (disp, vel, accel, incrDisp, incrDeltaDisp)

you are passing a list in the command when it does not take a list. use the following to do this:

set cmd "recorder Node -file $direction/Reigenvector-Mode$ModeNumber-Node$NodeNumber-x.out -precision 10 -node 1 -dof $a \"eigen 1 \""
eval $cmd
