hi;
i have some problem about algorithm and analyze. i modeled cantilever column. i took element properties from "column database"(http://www.ce.washington.edu/~peera1/proprect.htm) my code is failed and my results is different from test results. what is my code problem? i will send my code and please say me what is the solution?

Re: algorithm failed, analyze failed..
Try using Newton as a basic algorithm (instead of Modified Newton). Try variable transient instead of transient analysis.
Re: algorithm failed, analyze failed..
hi Vesna;
Thank you so much for your quick answer. i tried your suggestion, but it did'nt work. can you say me another solution, because it is really important for me.
do you think my code is wrong or not? what is the main problem?
i wait your reply,thank you..

Re: algorithm failed, analyze failed..
the fact that your analysis is stopping in the course of the analysis indicates stability of your model. since I do not know much about what you are trying to model I can not say anything about accuracy of your model. I noticed that you are modeling your column with only 2 displacement based elements (DBE). I am afraid that this is not sufficient. I would not model a column with less then 8 DBEs.
Can you tell me what is the second type of analysis that you are performing?

Re: algorithm failed, analyze failed..
hi Vesna;
The second type of analysis is dynamic analysis. (105.Saatcioglu and Ozcebe 1989, U3) experimental model has force-displacement test result. i don't know loading type,because test properties table don't have anything about loading procedure(it has only axial load 600kn), but i think this way; if i apply force data (this data is test result file) at free node, i can take displacement result, so i downloaded force.txt file.
then i applied this load like time series .
"set force "Path -filePath forceu3.txt -dt 0.02"
pattern Plain 2 $force {
load 3 1 0.0 0.0
}"
is it true?
if it isn't, what is the correct analysis type?
thank you..

Re: algorithm failed, analyze failed..
If you expect nonlinear behavior of your column this would not be a right way to define the load for your column. Why don't you try to find ground motion that they used in their test and use that one for your analysis.
Re: algorithm failed, analyze failed..
hi Vesna;
after your reply, i checked "http://www.ce.washington.edu/~peera1/" this site, and i didn't find any knowledge abaout loading type. then i wrote "Mike Berry and Marc Eberhard at the University of Washington". they replied me, they said; "The main result in the data file are indeed the applied forces and displacements. In general, the displacements are imposed on the column, and the forces needed to impose those displacements are measured (i.e., displacement control). There is no dynamic effect, since the displacements are applied slowly". i decided to apply force.txt file, and static analysis. i changed second type of analysis, i wrote new code usin tcl command.

i checked two data file, first is applied "forceu3",second is support reaction. both data file are same to number of data 217. then support reaction changed. what is the problem? what is the meanin of this error message? what is your suggestion? i'm waiting your reply Vesna.
Thank you so much,i'm grateful..
Re: algorithm failed, analyze failed..
If you want to simulate cyclic test you need to use displacement vector and assign it to time series. You can not go with forces. On the message board there are several topics that cover this issue.
