Re: problem with converge

Dear Vesna, i have the same converge problems in my model.
adding -iter option to the element didn't work.
tweaking the section worked well.
Thank you for your guidence.
Happy new year!

Hysteretic material

Dear all, I have two qustions about the Hysteretic material, 1. Is it possible to define more than three points for this material, i.e. 5 or 6 points? 2. If the answer of question 1 is NO. I am thinking about defining more points with the Parallel material. Such as: set matTag1 1; set matTag2 2; set...

Re: eigen analysis with or without gravityloads

Dear Vesna, Thank you very much. You are very warmhearted. The phenomenon i am saying is: The periods that calculated after gravity load is longer than the periods that calculated before gravity load. I think after the gravityloads are counted, the structure should be stiffer. consequently, the peri...

eigen analysis with or without gravityloads

Dear all, i find a strange phenomenon. for the eigen analysis, the period is smaller when the eigen analysis of a structure is conducted with gravityloads, compared with the period when the eigen analysis of a structure is conducted without gravityloads. the "Ex3.Canti2D.build.InelasticFiberSection"...

Re: remove recorder $tag?

Dear Vesna,
Thank you for replying me so quickly.
I revised the commander as:
"set tag [recorder Node -file Data/Eigenvector$i.out -nodeRange 1 46 -dof 1 "eigen 1"]
remove recorder $tag"
It works.
I appreciated your help.
Best wishes!

remove recorder $tag?

Dear all,
In the order of "remove recorder $tag ",
how the tag of recorder is defined?
ie. recorder Node -file Data/Eigenvector$i.out -nodeRange 1 46 -dof 1 "eigen 1"
how can i define the tag of the recorder?
Thanks.
