***ERROR: TIME INCREMENT REQUIRED
***ERROR: TIME INCREMENT REQUIRED
(OP)
I am modelling on composite beam with concrete slab on the top subjected to heat, when I use element S4R, the analysis run OK, when I change the element to S8R, ABAQUS could not complete the analysis and gave me the following error;
***ERROR: TIME INCREMENT REQUIRED IS LESS THAN THE MINIMUM SPECIFIED
I had my *.INP step as follow;
*STEP, AMPLITUDE=RAMP, NAME=MIN 1, INC=500, NLGEOM=YES
*STATIC
0.01, 1, 0.00001, 1
what should i do? please advice.

You could have problems with the meshing and the positions of the mid-side nodes (with distortion) to give you bad results, even if it were at only one node. Without looking at the mesh it's difficult to say. If you are looking to improve your accuracy and can't reason why 8 noded elements won't work then simply use a higher mesh density for your 4 noded linear elements.
If you have been able to get results at some time within the step, then look at these results. You might find that you have gross distortion at some point which causes the analysis to fail at the next time interval.
