I have been trying to generate a substructure in ABAQUS for a big diameter roller bearing. I have used two reference points, one each for inner and outer raceways to couple the inner and outer raceway surfaces. I have two steps in the analysis. The first step is Frequency followed by Substructure generation step. The analysis runs fine till the end of first step and calculates the eigen frequencies. When the second step starts, following error message appears.
" Element 439473 requires more than 2GB of memory for storage"
Element 439473 is just a point on the outer raceway and it is not used in any of the couplings. I have used continuum distributing couplings for coupling the reference points and the raceway surfaces. Following error also pops up after the element error.
***ERROR: An attempt to access admc buffer has failed. Any help would be truly appreciated.
Thanks in Advance.

Thanks for your time. But these links direct again to the same question which I have posted in other forums. Or did I look up wrong? The third link opens Abaqus 6.10 Manual.
in you history outputs remove nonessential default variables before running the analysis. for example, history will request multiple energy calculations such as strain energy, work, damping energy, .... Saving these calculations can burn your memory very quickly especially for dynamic models. Good luck!
Dear Sekar,
I have the same problema in Abaqus. I am doing mechanical analysis and the simulation is ended because according to Abaqus I have no space and the following error also appear:
*ERROR: An attempt to access admc buffer has failed. Any help would be truly appreciated.
I check my PC space and I think I have enough space.
How did you solve the problema.
Regards,
Ane
I had similar issue, I build the model in ANSA
the error was like this
"Element 19947 requires more than 2GB of memory for storage" and
"An attempt to access admc buffer has failed"
That element was not identified in the model; then searched for element id nearby say like 19944 - 19960 I found a few; deleted that complete face and meshed again
and launched it
No error
Some errors happen due to pre-processors; in my case it was ANSA issue
Hope this works to you
can you all tell which Pre-processor you were building your model in ?
Regards
Ali
Hi guys, I have the same error 'An attempt to access admc buffer has failed.'. Did you solve the problem?
***ERROR: An attempt to access admc buffer has failed
* This error is caused due to unnecessary space occupied in you Temp folder. Cleaning you TEMP folder and run the analysis again. If the error still contineous only option for you is to reduce the element count.
*If you are performing your analysis in you Local PC, you can expect this error often if you have more element count more than 3M. Try reducing your element count or if your in big organisation run it in the cluster which has more node, CPUs and high memory in C drive.
*This error may also be occure when using Hyperelastic material properties, which makes abaqus to use more spacing even with 1.6M element count. Its due to the background algorthim in abaqus
