The file you mentioned, Ansys.2025.R1.Products.Win64-SSQ.part24.rar, is part of a large multi-volume archive (typically 50GB+) of the Ansys 2025 R1 engineering simulation suite. Since it is just one segment (part 24) of a larger installer, it does not contain a single "solid feature" on its own.

Overall impression:
ANSYS 2025 R1 continues the platform’s tradition of delivering a powerful, integrated suite for multiphysics simulation, but it also introduces a number of usability and performance upgrades that make it feel more like a modern, cloud‑ready engineering environment than a legacy desktop package. For most users the upgrade is a net‑positive, though the price tag and the steep learning curve for the newest modules still keep it firmly in the realm of professional engineering teams.
