Abstract:

Throughout the years, ANSYS has dedicated to improve its products in every aspect. Starting R19, ANSYS has made some major enhancement on HPC. Let’s take a look.

 

 

Throughout the years, ANSYS has dedicated to improve its products in every aspect. Starting R19, HPC will be able to support PWM source in external circuit, non-constant time-step, and translational motion. If the number of unknowns in your project is greater than 500,000, a GPU can be utilized as well. In the previous version, R19 for example, GPU is used when number of unknowns is greater than 2Million. With the enhancement in the new R19 version, the speed-up is up to 2x or more in comparison with the previous version:

 

Matrix size CPU time

(8 cores)

CPU time

(8 cores + GPU)

R18

CPU time

(8 cores + GPU)

R19

Speed up
640,000 31s NA 25s 1.2x
1,293,170 2min47s NA 1min57 1.4x
2,260,365 4min4s 3min16 2min34 1.6x

One important aspect of HPC in this new release is that all ANSYS HPCs are consolidated, meaning that ANSYS HPC can be used in lieu of Electronics HPC as well.

Another good news is, ANSYS Mechanical, Fluids and Electronics licenses have 4 built-in HPC tasks enabling to run up to 4 parallel cores without requiring additional HPC licenses.
