Simple Frame analysis not working! I know this is simple!
Simple Frame analysis not working! I know this is simple!
(OP)
Hello...
I am new to ABAQUS and have a fairly straight-forward probelm (I hope!). i'm trying to model a simple 2D frame made of steel I-sections. I initially modelled it with rectangular sections without difficulty. However, when I changed the sections to I-Sections, it wont run! I have tried changing iteration parameters, to no avail. Section orierntation is (0,0,-1). Any other tips? It is pinned at the bases and has a signle point load applied.
I'd greatly appreciate any insigiht!
Thanks,
K

The error message reads:
"Too many attempts made for this increment
Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists."
And the .msg file says:
" ***WARNING: SOLVER PROBLEM. NUMERICAL SINGULARITY WHEN PROCESSING NODE
FRAME-1.1378 D.O.F. 6 RATIO = 9.63575E+009."
Thanks

I am using what I think is a very fine mesh (elements are 50mm long throughout the frame, whcih is 7450mm high and 30,000mm wide).
Thanks for any advice you can give!
I was wodnering if it might be something to do with the orientation?

No I have beam elements (B22 or B21 depending on the analysis) throughout the frame.

This is the problem...it works when the section properties are for a rectangle!
THanks for time! I really appreciate it...
