hi, Kamesh. thank you very mush for you concren.
i had a element that is ridid body motion in my model. do you think it is the problem? and how did you deal with it ?
If convenient, I hope we can communication with e-mail. My e-mail ID:kitefeifei@gmail.com.

hello,Kamesh9. i use the "puts" command to output a mark , in whic i find the error i got at the begining of analysis .
however,If it is in the elastic analysis, but also be able to explain what? or else?

hello everyone! :? the case i did is about the modes of pre-stressed concrete beam, but i got the WARNING!: "WARNING BandGenLinLapackSolver::solve() -LAPACK routine returned 17 WARNING AcceleratedNewton::solveCurrentStep() -the LinearSysOfEqn failed in solve() DirectIntegrationAnalysis::analyze...

in the rigid link command,beam means both the translational and rotational degrees of freedom are constrained.However,in the equalDOF command, the constrained is owe to what the $dof that you choosed.if you choose 1 3 (in the 2 ndm 3 ndf),the result of both that two command will be same.

hello，
Could anybody send The new version BuildingTcl via email to me?
my email address:kitefeifei@gmail.com
i would be thankful if you do it . thanks.
