New OpenSees version 2.4.6

[aenils]

Hi,

I just update the current version of OpenSees Program(2.4.6) before, I used version 2.4.5.
I run the pushover analysis in new version OpenSees but, I got the message as...

Trying Newton with Initial Tangent ..

My model works fine for version 2.4.5. I don't know what the message is for. Is there anyone to help me what the message is for? Is there any error to my model or it's just display message.
your reply will be highly appreciated.
Thanks

sorry .. a debug statement that got left in .. will take it out and put new version up next week

Hi All,

I'm currently trying to run a pushover analysis on a one story chevron frame, model fails before reaches target displacement. The following error message occurs:

You can try to increase the maximum strain if that is okay for your model
