Re: Capturing the step of analysis that a FBE fails
Thanks for the answers. You said: "I put a fix in the code for that.." Does it mean that if i download again the latest version i will be able to try it in my script and test if the warning message still appears? You also said: "..looking at the dW that were spit out when the problem ...

Re: Capturing the step of analysis that a FBE fails
When would such a message about ForceBeamColumn be a problem, only if there is no convergence at the end of the analysis procedure? If such warning messages appear for ForceBeamColumn elements, but at the end of the analysis procedure convergence is reached, is it something that we should worry about?

Re: Capturing the step of analysis that a FBE fails
So the warning message can't be reproduced..! Anyway, if a "capture" of what is appearing on the screen is what i wrote in my 3rd post: ... CTestNormDispIncr::test() – iteration: 1 current Norm: 0.00218257 (max: 0.01, Norm deltaR: 542.135) WARNING – ForceBeamColumn3d::update – failed to ge...

Re: Capturing the step of analysis that a FBE fails
Can you keep the 1 at the end of the test so you can view what i am saying in the screen in order to tell me if everything is o.k indeed :-) ? Maybe this warning message concerns only one iteration of the analysis step (in which it appears) and the "failure" finally doesn't take place at t...

Re: Capturing the step of analysis that a FBE fails
As i said, the analysis procedure finally ends succesfully but before it ends the warning message that i wrote in a previous post appears on the screen (while all the steps are appearing one by one on the screen, in one of them this warning message appears and after that step the procedure continues...

Re: Capturing the step of analysis that a FBE fails
I run the script in the latest version (2.4.4 rev 5730) and it is the same thing as before. You should watch the process of the analysis (when the steps are keep running) and the 'failure"(?) occurs somewhere between the middle and the end.

Re: Capturing the step of analysis that a FBE fails
So, the version i am using it isn't the latest... I will try to work with the (real) latest and i will let you know (probably tomorrow because here is late midnight right now...). Thank you

Any conclusion about this matter? (Did you receive the script?)

Re: PDelta transformation affects on eigen analysis
If you apply gravity loads and then perform an eigen-analysis, if your elements are defined through fiber sections it would be normal to obtain different eigen-values because the stiffness of the structure isn't the same comparing with the case that there are no loads at all in the structure... When...
