Hello,<\/p>\n

I am solving a Fluent case, with activated “Structure”, which means that I use Fluent intrinsic fluid-structure interaction solver. 
I experience the same solving time, when I use single core, and multiple cores (e.g., 16).
I checked the partitioning details, shown below:
<\/p>\n

For the fluid flow-only Fluent simulations, I always got faster computations with multiple cores.
Do you have any advice, how to overcome this issue, maybe with tuning parallel settings? When I checked the CPU usage in the Task manager, I can see the higher CPU usage for the multiple core Fluent solving (proportional to the number of cores). Therefore it is clear that the solving takes action on the multiple cores, but it is not faster than using single core.<\/p>\n","protected":false},"template":"","class_list":["post-362187","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
