SubscriberTrying to analyze a structural module for large deflections and got the below error.
*** ERROR *** CP = 731.672 TIME= 23:34:24
There is not enough memory for the Distributed Sparse Matrix Solver to proceed using the out-of-core memory mode. The total memory required by all processes = 805117 MB. The total physical memory that is available on the system = 15403 MB. Please decrease the model size, or run this model on another system with more physical memory.
The same model ran successfully when the large deflections option is off.
We have multiple base load cases and with large deflections 'on', some cases it is solving successfully but some it is throwing out the memory error.
The error is very strange and it is asking for 805GB. System RAM is 16GB and in Hard-disk around 220 GB space is free.
Kindly help me in resolving the issue.

Ansys EmployeeHello
This usually indicates the model is not constrained. Try adding some fixed supports to see if you can at least get a solution to see where the problem is.

Ansys EmployeeHi @bharath_reddy1 also did the linear solve (large deflections turned off) use the Iterative solver? It requires about an order of magnitude less RAM than the Direct (Sparse) does. You can try specifying the solver type to be Iterative in the Details of the Analysis Settings, on the large deflection model, and see if it will solve or not.

Thank you for response. Next time we will use the option that you have suggested.
However, I did a try with an increase tolerance to 2% and it solved all the load cases. Please see below screen shots of the analysis settings. Please advise any changes we can make to improve the solver time and maintaining the accuracy in results.
Also advise on the help document where i can find the use of different options available in Newton-Raphson. Currently i have randomly selected as unsymmetrical
Please see the image below on the Analysis model that i am trying to solve. It is having (a) basic load cases and (b) solution combinations in it. To solve basic loads cases - for each case it is taking more than 1 hour.
This is the 1st time i am using Ansys to perform analysis for these kind of structures (We regularly use SACS for these king of global analysis). My experience in Ansys is just since last 45 days. I have developed ansys load cases and combinations based on past SACS experience. Please advise if there is any betterway to handle these things in Ansys so that the solution time can be reduced.
Please let me know if you need analysis files for your review.
Best regards Bharath

Ansys EmployeeHello Luc,
We would suggest to raise a new discussion instead of posting in old threads. To add to above comments by Gary and Mike, check if your model is properly constrained. And here is a forum discussion link which might help you to solve the issue.
Regards,
Nanda.
