Ansys Products 2024 R1 Global Release Notes

1. Advisories
The Microsoft Defender Antivirus program in Windows Security, on Windows 10 and 11, will scan all executables associated with the Fluent and Mechanical products and can cause some performance issues. A workaround consists in adding an exception in Windows Defender for the impacted Ansys executables.

2. Compatibility with Previous Releases
Backwards Compatibility: Ansys 2023 R1 was tested to read and resume databases from the following previous versions: 2021 R1, 2021 R2, 2022 R1, and 2022 R2. Note that some products are able to read and resume databases from releases prior to 2021 R1. For those products that cannot directly read an earlier database in 2023 R1, first resume it in a supported version and then resume that database in 2023 R1. Upward/Forward Compatibility: No previous release has the ability to read and resume a database from a more recent release.

3. Documentation
Ansys Help cannot be launched from Firefox on Linux in a DCV environment for the products CFX, En-Sight, and Polyflow.

No Workbench verification test cases have been removed.
4.3. LS-DYNA Verification Manual
LS-DYNA Fluids Test Cases
- VM-LSDYNA-FLUID-005: The Poiseuille Flow - Steady 3D Laminar Flow in a Pipe: This test reproduces a three-dimensional, steady, incompressible laminar flow in a pipe: the Poiseuille flow. The purpose of the test case is to validate the pressure jump between the pipe inlet and outlet.
- VM-LSDYNA-FLUID-006: Steady 3D Laminar Flow around a Cylinder in a Channel: This test case reproduces a three-dimensional, steady, incompressible laminar flow around a cylinder inside a channel. The purpose is to validate the drag and lift force coefficients and the pressure difference between the front and end points of the cylinder.
- VM-LSDYNA-FLUID-007: Unsteady 3D Laminar Flow Around Cylinder in a Channel: This test case reproduces a three-dimensional, unsteady, incompressible laminar flow around a cylinder inside a channel. The purpose of the test case is to validate the maximum drag and lift force coefficients and the pressure difference between the front and end points of the cylinder.
LS-DYNA EMAG Test Cases
- VM-LSDYNA-EMAG-007: 2D Axisymmetric Inductive Heating: A heated coil is wrapped around a cylinder. The coil carries a sinusoidal current. The goal is to determine the temperature at the bottom center of the cylinder where the temperature sensor is located in the experiment.
- VM-LSDYNA-EMAG-008: Magnetostatic Force Calculation: This TEAM 20 problem is a non-linear, magnetostatic, 3D model designed to verify magnetostatic force calculations. The model allows you to investigate surface magnetic force calculations obtained by the LS-DYNA monolithic solver in magnetostatic cases under different current excitations. The goal is to determine flux densities at specific surface points within the model as well as the magnetostatic force for different values of ampere-turns.
