Reply To: ANSYS Student 18.2 MPI Blocked?

[tbb16]

Thanks for your reply. My understanding is that the solver has always been limited to using physical cores when using Mechanical (static problems etc). I am doing explicit analysis which uses the AUTODYN solver, and can easily be distributed across multiple cores. I have always used hyper-threading for explicit and get around 30% increase in performance when doing so (I have tested this extensively). I was just wondering why ANSYS have now blocked the MPI (at least, blocked it on the AUTODYN solver) as I lose that extra 30% performance, which is a lot when simulations run for 5+ hours.
