Hello everyone, 

I'm currently running an Abaqus Explicit Analysis (with import procedure) but I'm facing some constraints related to the amount of CPUs that I can use, which is making the analysis time unpractical. 

The problem is basically this: whenever I try to use a certain amount of CPUs (let's say 48) above a certain limit (24, from what I've checked) I receive the following Abaqus error: Signal 11, which doesn't give me any clue of what is happening on .dat or .msg or .sta. 

I imagine that the error is coming because I'm requesting more processors than the number of domains created but I'm not sure if that is really an issue or not. To give a background, my model contains ~600k nodes and 350k elem. and there is one region with tie/constraint with ~42k nodes and 16k elem.

Has anyone faced the same problem? Is there a way to change the constraints or tie to something that can be split across domains? Are there any parallelization strategies that I could try to use to overcome the problem? 

Thanks in advance for your suggestions!
