Are there any services that can help with analysis of a mid- to big- sized ANSYS file? The model has ~700,000 nodes, with a mesh quality of 0.75. The model has contact surfaces. We are currently running the analysis on a dual core license. Would like something faster.
 
Bluebulb,
Good day, here are my suggestions about your case:
1) If you have the resources, I recommend you consider Quad-core to 8-Core CPU's
2) If you're limited to your current equipment specification, try manipulating ANSYS Customization/Preferences (use Graphics Device Name other than "3D") and in High Performance Computing Setup, maximized the number of processor that can be utilized.

Hope this help.
Regards
 
Helo bluebulb,

as I understand, since you are asking for a service, you need some one else run the model for you.

I can help you with that.

Regards,
Alex

Tuning Your Simulation
 
Bluebulb,

Before you invest in any other machines, what kind of license do you have? Though more cores will help a computer in general, if you only have a two-processor (cores and processors are synonymous in licensing for ANSYS) then it will only indirectly assist your analysis time.

Assuming that there are no changes such as expanded domains or symmetry that you can use to expedite your analysis, then without new equipment or a license change you may need a new service. Make sure you weight the cost of a new machine and even a temporary license increase against the service, since new equipment can make your life easier in the future. Especially if you already have all the FE and set-up work for your modeling basis complete.

Noting your mesh quality, I want to ask - what kind of analysis are you doing? If there is any electromagnetic or fluid simulations in particular, sometimes refining the mesh further can actually save you time over all. :)
