LOAD STEP doesn't converge in ABAQUS
LOAD STEP doesn't converge in ABAQUS
(OP)
Hi everybody!
I'm modeling a RC slab under fire condition in ABAQUS.
The thermal analysis result is correct and converge, but when I want to do a Static analysis I create a LOAD STEP (where there are only static load) and it doesn't converge anymore.
The ABAQUS error is: TIME INCREMENT REQUIRED IS LESS THAN THE MINIMUM SPECIFIED
I have a TIME PERIOD: 1800
Initial increment 60 minimum 5E-2 max 60
Why it doesn't converge?
Regards

RE: LOAD STEP doesn't converge in ABAQUS
Try dropping your minimum increment down a bit and see what happens. You should also double check your model to make sure it is fully constrained, your material properties are correct, your loading is properly setup, etc. You gave a very vague description (without pictures) of your model, so there are numerous possibilities of the problems.

The analysis consist in a thermo-mechanical analysis of a RC slab under fire conditions.
I made a thermal analysis before and then I use the temperature results to start a static analysis with material non-linearities (I'm using a CONCRETE SMEARED CRACKING model for plasticity).
I can't understand why it doesn't work. (Other analysis work perfectly with this range of STEP: min 5E-2 max 60)
Thank you

Ah ok. So that could be the problem?
I will try it!
Thank you all for your tips!
