Hello,

I got complex building and i cannot apply the permanent load.
PRograma gives me the following msg:

Permanent Loading
-----------------------------------------

LF= 0.00000, LF_incr= (Iter: 2 => fbd_Ite)
LF= 0.00000, LF_incr= (Iter: 2 => fbd_Ite)
LF= 0.00000, LF_incr= (Iter: 2 => fbd_Ite)
LF= 0.00000, LF_incr= (Iter: 2 => fbd_Ite)
-----------------------------------------
Unable to apply the entire permanent load. Analysis terminated

How can i find my error ?
Thanks

A forum search on "fbd_ite" will produce a sufficient number of hits to begin tracking down the problem hrodrigues.

A Help System search on the same term will also provide some valuable information.

This is always the best place to start when problems like this arise. Perhaps another user has encountered the same problem and suggestions previously made would apply to your situation as well.

Of course, it is still possible that the source of your error is something new, but it's best to at least try these avenues first.

Best of luck

Yes, as noted by huffte, a search on "fbd_ite" or "convergence" or "convergence difficulties" will indeed lead to a myriad of Forum posts with plenty of tips & hints on how to tackle such problems.

Amongst those many suggestions, we cannot but to emphasise the pertinence of starting the model debugging exercise on a smaller and simpler subset of the larger and more complex model, and then incrementally add new elements/features until the cause of the convergence difficulties is identified.
