I'm running ABAQUS Explicit analyses. I faced a problem which I hope someone here know a solution to it. My analyses take something like a day or a day and half. Initially the jobs take about half of my physical memory (RAM) but as the analyses progress forward the jobs consume over 95% of memory and makes everything run slow. I must add I use VUMAT too but my subroutine doesn't need any array and I'm pretty sure that every variable that is defined in each call would be ultimately released at the end, at least that's the way it should be. I don't even use SAVE identifier in my fortran code. I would really appreciate any help in case you already had such situation and have a clue what the cause could be.
I use memory option at the command line but apparently it is inconsequential to the way memory is consumed during an analysis
