I have a relatively simple model in RISA-3D. No "tension only" members. No "Euler Buckling" members. Spring constraints and some RIGID members, though.
It's got a few HUNDRED load combinations, and I'm trying to run ONE, using the "Solve Current Combination" command.
So far, so good.
Here's where it gets weird:
Load Combo 213 runs the DL, scaled by 2.0, plus BLC8, scaled by 2.0
Load Combo 214 runs LC213, scaled by 1.2
BOTH LC213 and LC214 run without problem.
Load Combo 219 runs the DL, scaled by 0.9, but NO OTHER load cases added
Load Combo 220 runs LC219, scaled by 1.2
NEITHER LC219 NOR LC220 runs!! After a few minute's iteration, I get the following error message:
"Solution could not converge while solving: [Load Combination Name]
Please review your model. Solution stopped!
Error code = 1162"
Why does the SAME MODEL work for a MORE COMPLICATED Load Combo, but not the simpler one???!?
Thanks.
