ANSYS has problems with EPYC 7742 CPU!!!
 

I bought dual EPYC 7742 server for CFX simulation!

OS: Windows 2016 Server.

After, I knew ANSYS had some problems with EPYC 7742 CPU.

CFX does not start sover-mpi.exe very frequently!

ANSYS Linux version does not have any problems with 7742 CPU.

Later, I become to know Windows CFX is using old Intel mpi version than Linux version.

Windows Version ANSYS is using 2018 version Intel mpi.

User can not change Intel mpi version in CFX.

I already informed this problems to ANSYS about 2 years ago.

ANSYS knew this problem but did not make any actions for solving this problem.

In the same conditions, Intel server does not have any problems.

ANSYS! release modified version immediately!
