Hi Artur,

Thanks for all your help.  I've certainly learnt a few new tricks.

I've used your suggestions from this post to create a complex model. (beam division option and the detailed correction tool).  

The correct drawing model and detailed drawing model don't always seem to work, but for those few cases i just moved the nodes ( the ones causing the instability) manually.  

In some cases the snap seems to get confused.

I found that the non-linear analysis can be changed to a linear analysis through the analysis>analysis type window. 

If you still want to see my model send me a private message.

Thanks Again.

I found that the non-linear analysis can be changed to a linear analysis through the analysis>analysis type window. 

Only when it is set manually rather than caused by some 'non-linear' object defined in the model

If you still want to see my model send me a private message.

If you solved all the issues then I'd rather try to focus on other cases that need our assistance (I hope you don't mind). In case there is still something to have a look at let me now please and I'll contact you using the private message.

Hi huyxp,

you need to add the corresponding section database (British sections UKST)

Try Tools -> Job preferences -> Databases -> steel and timber db -> Adding new database to the list ... see picture
