how to restart an interrupted analysis
how to restart an interrupted analysis
(OP)
Hello Everybody,
I am runiing an fsi model for 40 seconds, but after some times running like 0.2 seconds for both solid and fluid, it hangs, and if I continue this way after 8-9 hours every window vanished showing that "your computer is low on memory".
Recently I have found that when before everything stops, (when the computer is already in hanged condition), the msg file of solid is increasing in size. Even when it stops working, I checked the msg file, I saw that, it completed running more than my expectation. So I think that, actually it works at that time, although it did not run upto the total time period. But after everything in stopped, I saw a notice in the taskbar that shows "would you want to restart or close your program" and i clicked on restart and it started running again. Is that called the restart analysis? If it is, then can I run the program after it shuts down form that point at which it stopped running? Can anybody tell me how to do that?
I have studied the manual but at some points I am not understanding. When newly tried to restart again, I went to the output tab in the main menu,in step modeule and found that there is an option of restart. When I clicked on that, it showed that the frequency is zero. How to change it, can you explain please?
For the recent days, after the program shuts down I don't see the close or restart option any more. The computer is not showing them anymore. Thats why I am not able to run it anymore from that stopped point.
Any reply would be of a great help.
thanks

I don't know what software is involved in this question and I suggest the OP asks the software support people.

Thanks for your reply.
I am running abaqus 6.12 and in a workstation 32 GB ram computer. I have heard some people did this kind of things. That's why I have my question. At least it should be done from a definite time increment number at which the analysis had been stopped.

a) A user to stop the run and maybe continue it at a later date or on a different system (i.e. a different host or set of hosts).
b) Change the simulation parameters (e.g. activate outputs).
c) Recover from a known, good state if things go wrong (typically massaging the timestep size to get over unstable or stiff parts of the simulation).
Some simulation systems allow you to resume from a post-processing file.
Some simulation systems allow the option of a continuation restart or the use of a restart (or post-pro) file to be used as initial conditions for a new simulation.
You need to get your vendor to help with the specifics. I'm guessing that the fsi model is coupling two solvers together at a timestep interval, so there may be some fiddling around getting two solvers to restart in unison.

Let me see what I can do. Thanks for your reply.
I reduced the number of outputs so that it can save some memory, but it is not working still. Even I have reduced the mesh size a lot. But no result.

At first I thought so, but I could not find something like that. I am still trying.
