Workstation PC Build for Large Deformation Finite Element Analysis (Explicit)
(OP)
Hi Everyone,
I am currently thinking of building a new workstation PC for ABAQUS Finite Element Analysis, I am running ABAQUS CAE 6.12 on my computer with these specifications:
CPU: Intel Core i5-4690K 3.5GHz Quad-Core Processor 6MB cache
GPU: Nvidia GTX 970 4GB GDDR5
SSD: Samsung 850 250GB 2x (Raid 0)
HD: Seagate Barracuda 1TB
RAM: Corsair Vengeance 1600MHz DDR3 CL9 16GB
The simulation is taking days and I am wondering if it is it worth building a workstation PC with 32GB of DDR4 memory and an Intel Core i7-5820K 6 core processor with 15MB cache to reduce computational time? I am doing a Large Deformation Finite Element Analysis (Explicit) using the Coupled Eulerian Langragian(CEL) method. Feedback from others who have done FE analysis (Explicit) using abaqus on workstations vs servers or desktops would be great!
Thanks For taking your time to read this!

If you are in academia there are often state-funded HPC providers that will support your research free of charge (i.e. give you access to a cluster).
Otherwise I would exploit every possible method of reducing your analysis time and stable time increment before committing to the investment.

Coarsening the Eulerian mesh is not really an option as I will have to do a mesh convergence analysis. I don't have access to HPC in my University so I think I should probably just let my computer run constantly and hope for the best as it seems like there is not that much I can do and Hiring a cluster seems a little out of my personal budget for my thesis.

By the way, one second is a LOT of time for an explicit scheme (which is what CEL uses), particularly with the kinds of element sizes and numbers involved in CEL analyses. Half a second or less are typical times for such analyses.
In addition to previously mentioned workarounds, you might also wish to look in to BCs such as non-reflecting ones for a smaller Eulerian domain. Also, you can be clever about your mesh seeding so you have a fine mesh only in areas of high interest.

This is a problem for the implicit scheme, most definitely NOT explicit.

By the way, check out the Director's Allocation Scheme at Pawsey. It may not be much but it may very well be an order of magnitude or two better than your set-up. https://portal.pawsey.org.au/docs/Supercomputers/S...

If your computational time is going to limit the amount of useful work that you can do, you should consider simplifying your analysis. If you are only interested in the behavior of the anchor, for example, could you make some sort of simplifying assumptions with regards to the loading and run a static analysis instead?
