Altair AcuSolve 2024 Release Notes
Highlights
- Velocity Magnitude to OSI data
- Heat Flux to standard nodal output
New Features
- Velocity Magnitude to OSI data
- Velocity magnitude is now available under the surface integrated output list of data. This resultant vector magnitude is available for plotting of 2D data.
- Heat Flux to standard nodal output
- Heat flux was previously available from the extended nodal output list,
requiring you to request and load additional data that might not be
needed for all simulations.Note: This variable has been moved to the standard list of nodal field data and can be accessed without the need to load extra data.
Enhancements
- Large model domain decomposition is now available on Linux using PT-Scotch libraries, currently accessible via a cnf parameter.
- Documentation Additions
- The Training Manual section of the AcuSolve documentation has been reorganized. While the Introduction and Theoretical Background sections remain largely unchanged, a new section, simply titled AcuSolve has been added. This new section includes a wealth of information from the general workflow of creating models for AcuSolve, to solver specific information about convergence criteria and the format of time statistics at the end of the Log file, to sections dedicated to specific physics areas supported by the solver. The various types of boundary conditions available in AcuSolve, along with their respective applications and usage scenarios have been documented in the AcuSolve Training Manual. Additionally, a new comprehensive explanation of the Atmospheric Boundary Layer (ABL) inlet boundary condition has been incorporated into the Training Manual under the section of boundary conditions. This addition includes the general description of the ABL inlet condition and the wind velocity profile equations alongside turbulence equations. Finally, new sections covering radiation modeling with participating media and mass transfer with AcuSolve/EDEM bi-directional co-simulation have been added.
