Altair ultraFluidX 2021.1 Release Notes
Enhancements
- Library updates and additions (CUDA, Open MPI, and UCX)
- ultraFluidX 2021.1 utilizes more recent versions of CUDA (version 11.2.1), Open MPI (version 4.1.0), and UCX (version 1.10.0).
Resolved Issues
- Turbulence model contribution to the total viscosity was missing in several secondary parts of the code.
- Formation of a pressure wave at the end of the overset ramp-up phase.
- Voxels inside under-resolved gaps and grooves with rotating boundary condition did not receive a wall velocity contribution.
- Potential surface mapping issue for baffle parts that created non-physical values on the baffle surface.
- Post-processing error caused by empty files for partial surfaces and monitoring surfaces of an overset mesh simulation.
- Unexpected mesh refinement pattern close to the wall for a wall-normal refinement interface.
- Time- and window-averaged velocity values were unavailable in the monitoring surface output.
- Incorrect order of boundary conditions and flow computations in the mesh transition region.
- Excessive output of monitoring surface variables in effective solver deck.
- Potentially asymmetrical effective domain bounding box in y-direction.
- Potential dependency of results on the number of GPU devices for cases with MRF.
