switching to only 8 cores without gpu accelleration it take significantly longer to solve but the writing time is normal. althout i get this warrning:
*** WARNING *** CP = 5295.719 TIME= 14:05:32
During this session the elapsed time exceeds the CPU time by 71%.
Often this indicates either a lack of physical memory (RAM) required
to efficiently handle this simulation or it indicates a particularly
slow hard drive configuration. This simulation can be expected to run
faster on identical hardware if additional RAM or a faster hard drive
configuration is made available. For more details, please see the
ANSYS Performance Guide which is part of the ANSYS Help system.
Total CPU time for main thread : 3178.6 seconds
Total CPU time summed for all threads : 5295.7 seconds
Solver uses 25GB out of 64 avelible RAM, i think partialy long elapsed time is due to contact element and fracter parameter creation, can it be righte?
But still it dasn't explain why with gpu accelleration it take 3-4h to "write results file".
PS. i have Samsung evo 970 Pro SSD drive
