In previous versions of Abaqus (version 2021 and below) in Windows, the maximum CPU capacity is used by setting the number of cores and threads. In the new versions (2022 and 2023) with the same settings, only 20-50% of CPU capacity is used. How to use MPI in Windows? The latest version of Microsoft MPI can be installed in the link below.

Hi, Abaqus supports Microsoft MPI out of the box. If you have any problem with it that please contact your local SIMULIA support provider or ... switch to Linux and OpenMPI ;)
