Altair nanoFluidX 2024.1 Release Notes

Highlights

Dedicated tank slosh solution in SimLab.
Body frame (inertial reference frame) now supports all 9 velocity and acceleration terms.
Latest NVIDIA GPUs are now supported. Kepler generation GPUs are no longer supported.

Body frame (inertial reference frame): The new body frame feature provides more options for defining inertial reference frames. In addition to the existing linear acceleration terms, angular acceleration and angular velocity can be defined and activated as required by the simulation. This capability primarily expands performance types for tank slosh simulations.
SimLab 2024.1 tank slosh solution: SimLab now offers a dedicated solution and ribbon menu for creating tank slosh and filling simulations, simplifying setup.
Multiple surface representations per solid phase: Multiple STLs can now be assigned to a single solid phase for visualization via a dedicated section in the solver configuration file. These individual surfaces can then be hidden or shown separately in the post-processing stage, providing greater control over visualization.

Support for latest NVIDIA hardware: The solver build procedure was updated to take advantage of the latest NVIDIA GPUs. This increases the minimum NVIDIA driver version to 525.60.13 on Linux and 528.33 on Windows. GPUs based on Kepler architecture are no longer supported.
Help updates: The nanoFluidX help Get Started section was restructured and the individual chapters are now up to date. A new water management solution tutorial video is available.
ParaView support: ParaView 5.12 is now supported by nanoFluidX state files.
Single precision updates: Motions are now more robust with respect to round-off errors when using single precision binaries. The recon (restart) procedure was updated, which means that Restart/Continue with recon files from previous versions is not possible.
CPU affinity: CPU affinity can be automatically set based on GPU round-trip time on Linux.
