ABAQUS Fluid-Structure Co-simulation keeps crashing/Program not responding
ABAQUS Fluid-Structure Co-simulation keeps crashing/Program not responding
(OP)
I have no idea why this happens, but I've been pounding at this the whole night. I have a Fluid-Structure co-simulation all set up and ready to run. It does ok for about 3000 iterations, and then at a certain total time ABAQUS stops responding. What does this mean when this happens, is the solution blowing up/not converging, or is there something else happening?
Another thing is that I keep having the problem of ABAQUS disconnecting from the License Server after 3600 seconds, is there anyway to disable this?

RE: ABAQUS Fluid-Structure Co-simulation keeps crashing/Program not responding
First off, thanks for your response in both my threads, you've been a major help. I'm currently running a local installation of ABAQUS 6.12 Research Edition on my lab computer, but the problem keeps surfacing at approximately the same point. I have had solutions blow up so I know what to expect when I monitor the Divergence values, but it's just mind-boggling when the program just stops responding altogether.
RE: ABAQUS Fluid-Structure Co-simulation keeps crashing/Program not responding
Just to be sure, a particular model halts both with a the networked license as well as a local license, correct? What message(s) do you see in the command prompt (if you run your model from the command prompt)? If you do not run it from the command prompt, I suggest you do that and make sure nothing else is running on the machine (browser, editors, unnecessary services, etc.) For a local installation, the only thing I can think of is that may be the hardware isn't up for the task.
By the way, does this happen with other models as well? If you have a previous model that has worked, try running that one (if you haven't already).

RE: ABAQUS Fluid-Structure Co-simulation keeps crashing/Program not responding
Come to think of it, it might actually be a networked license. The command prompt that shows up says it gets some license from the school's network. Would that affect how ABAQUS is run?
RE: ABAQUS Fluid-Structure Co-simulation keeps crashing/Program not responding
Yes! If the connection drops, or, if the hardware is being used to its max. capacity preventing proper communication over the network with the license server, or if the server is down etc., that will affect how ABAQUS functions.
You should not see experience this in a local installation, however.

By the way, you are not using any user subroutines, are you?

Flow through a bent tube, but I modified the parameters for my case as necessary. The only thing I left out was
*Controls, type=FSI
, , , 1.1
In the *CO-SIMULATION CONTROLS part. Is that necessary? The user guide doesn't exactly elaborate on what that does. MY density ratio is much, much higher than 1.1 though.
