can you post the section and materials commands

Re: How to check if the analyze is completed?
set ok [analyze 1]
puts $ok
will output 0 if it worked, other number if did not.

Re: Applying an earthquake acceleration to model
when you used uniform acceleration it does not apply any acceleration to the base nodes .. what it does is create a forcing function F(t) = -ag(t) M 1, M being the mass matrix and ag being the ground motion and 1 a vector of 1's and 0's, 1 in the vector if the corresponding dof is in the dirn specif...

Re: Applied displacement
are you basically saying that the acceleration recorded at the ground node is not the same as that you used to derive the displacements?

Re: Region
you can build up the element or nodes into a list and then put an eval around the command
set cmd region -ele $eleList ....
eval $cmd
set cmd region -ele $eleList ....
eval $cmd

Re: Why does not the period change even though shear is incl
sorry .. shear aggregator does not work with disp based elemnets, only forced based include shear defo effects if provided in the section.

Re: Record flexure and shear displacements components
you cannot record that info from the element .. and your approach will not work for a nonlinear model.

Re: Viscous damper with MultipleSupport disp input
the viscous material is looking at change in vel of two connected nodes to get a force value .. as you only provide an imposed displacement at the node and no associated vel, the material is going to have a 0 force as there is no delta velocity between the nodes.

Re: Algorithm Failed at Iteration
if the solver fails it means the tangent matrix is singular, i.e. a 0 encountered on diagonal during factorization, i.e. your model is unstable. .. as it does get through the first few steps you could try swicthcing to a ModifiedNewton with initial stiffness iterations

Re: ConvergenceTest object failed in test
the message says that after 100 iterations it failed to reach the convergence that you specify of 1.0e-5 on the norm of the disp increment, at the 100'th step the norm was 14.4 and the norm of the unbalance was 36.9. as it is failing in the very first analysis step .. your model is probably incorrect.

Re: Error while building OpenSees source code by Visual Stud
no .. it is looking for a lib it cannnot find .. look to see in the opensees project settings where tcl86t.lib is being set and try changing to tcl86.lib or whatever the lib you have is.

Re: Develop a material/opensees
you could place a link to the dll in the wiki. you need my permission to get wiki page access. it will of course be useless when we update to newer versions.
