The "Win64" indicator specifies that this suite is compiled for 64-bit architectures of Windows—specifically Windows 10 and Windows Server 2019/2022. This is critical because modern FEA and CFD simulations routinely exceed the 4 GB memory limit of 32-bit systems.
ANSYS claimed up to 2x faster frequency sweeps in HFSS and 30% faster direct sparse solves in Mechanical compared to 2021 R2. ANSYS.2022.R2.Products.Win64-SSQ
: SSD storage (at least 256 GB) is suggested for smooth operation. The "Win64" indicator specifies that this suite is
: Expanded support for thermoelectric and piezoelectric coupling in static and transient simulations. ANSYS.2022.R2.Products.Win64-SSQ
The string ANSYS.2022.R2.Products.Win64-SSQ refers to a specific distribution of the Ansys 2022 R2
