Abaqus - ABA_SINT_CAP over 16Gb

Hello !

I'm currently making a large model to that simulates a lot of contacts in-between beams (a cable analysis), and I reach the 16384Mb maximum with ABA_SINT_CAP, withmodels that are still too rough/too short to be useful.

***ERROR: MAXIMUM SIZE OF STATIC WORKSPACE HAS BEEN EXCEEDED. CURRENT 
WORKSPACE SIZE IS 16384.00 MB. THE SIZE OF THE WORKSPACE CAN BE 
INCREASED USING THE SYSTEM ENVIRONMENT VARIABLE ABA_SINT_CAP.

I define contacts domains for all pairs of beams that may come in contact. I also still have plenty of available memory on my workstation, I'm currently using a maximum of 150Gb with a total of 512Gb of RAM.

Is there anyway to raise even further this memory cap ?
What consumes so much of this "static workspace" memory ?
If I refine my contact domains to be even smaller, will I use less "static workspace" memory ?
What are the good practices to reduce the used "static workspace" memory ?
Also, is there any official documentation on this variable or what exactly is the "static workspace memory" ? I can't find anything that even mentions the ABA_SINT_CAP elsewhere than in forum posts.

Many thanks !
