25.3.0

New Features

  • A data-driven real-time simulator creation feature has been added. Using data created via batch run functionality as a snapshot, it generates a Reduced Order Model (ROM) to produce results for arbitrary conditions in real time.
  • Some dynamic mesh features have been enhanced in the NextFOAM code, and dynamic mesh functionality has been incorporated into the density-based compressible solver.
  • We have enhanced usability by adding suffix to project folders. Since Baram projects are managed as folders, there was inconvenience in distinguishing between regular folders and Baram project folders, as well as between the baramMesh folder and the baramFlow folder. To resolve this issue, we have added an option to use the .bf and .bm extensions in the project folder names.
  • The performance curve input method for fan boundary conditions has been changed from velocity-pressure to flow rate-pressure, and the data input method has been modified to allow copying and pasting data from spreadsheets.
  • New Boundary Conditions
    • Flow Rate Outlet: You can now define the flow rate at the outlet of the flow.
    • Intake Fan, Exhaust Fan:Fan conditions can now be applied to the inlet/outlet boundary surfaces of the flow.
    • Wall Layer for Baffle: When modeling a thin solid within the calculation domain as a thicknessless baffle, the effect of thickness can be simulated through one-dimensional heat conduction calculations.
  • New material properties setting method
    • The Boussinesq approximation can be used for density calculations.
    • A method utilizing NASA’s thermodynamic database, Janaf, has been added for calculating heat capacity (Cp), enabling the expression of Cp as a function of temperature under ideal gas conditions.
    • Perfect fluid conditions can be used to calculate the compressibility effects of liquids.

Improvements/Bug Fixes

  • When calculating force, the method has been changed from using absolute pressure to relative pressure. When calculating forces acting on boundary surfaces, external forces are now calculated using the reference pressure, enabling more realistic force values.
  • An error preventing the solid’s heat capacity (Cp) and thermal conductivity from being specified as polynomials has been fixed.
  • An error causing parallel computation failures at specific core counts in multi-domain combined heat transfer problems has been fixed.
  • When copying boundary conditions, boundary surfaces are now sorted alphabetically by name.
  • An error causing graphic widgets to duplicate when saving a project under a different name has been fixed.
