CstateFlag

[xantis85]

Hello,
I would like to know the "state flag" for the Limit State Material in real-time during a Nonlinear Time History analysis (i.e. if the limit state curve has been reached for the element considered).
The "print" command allow to plot at each step something similar:

Element: 1111 type: ZeroLength iNode: 11 jNode: 111

I'm only interested in the "CstateFlag" for the "LimitState Material, tag: 3111", but i need this variable step-by-step in order to stop the analysis when a particular condition has been reached.
Is that possible to record in each step of the analysis the CstateFlag?


Thank you in advance for your help.

i made a slight mod to the code .. if you download the current version you should be able to ask for "stateFlag" from the limitstate material

Could you please write which command sintax I have to use to ask for stateFlag?

Thank you in advance for your help.

normal element recorder and instead of strain or stress at the end of the command put stateFlag

[xantis85]

I'm trying several combinations for the recorder, but I've no output. If I have a zerolength element with tag 1111 and the tag for shear limit state material associated to this element is 3111, in order to record in real time the CstateFlag, have I to write:

set CstFlag [eleResponse 1111 stateFlag] or set CstFlag [eleResponse 1111 material stateFlag] ?

[fmk]

neither .. you need the material # in the command (zeroLength can take multiple materials) if only 1 material

set CstFlag [eleResponse 1111 material 1 stateFlag]
