Release Note-v26.2

v26.2.4

June 23 2026

Bug Fix for User Parameters in Batch Runs – Starting with v26.2.0, we have fixed a bug that prevented users from entering user parameters for AoA and AoS at the Far-field Riemann and Freestream boundaries, as well as for latitude at the ABL boundary.

In the baramMesh “File” menu, selecting options such as “New,” “Open,” “Open Recent,” or “Save As” closes the current project and opens a new one. Previously, if the program was unable to open a project for any reason, it would enter an abnormal state and fail to function properly; this issue has now been resolved.

Fixed an issue where Geometry Transform did not work in baramMesh
Fixed an issue where the Graphic Report did not work when using the turbulent transition model

May 26 2026

An error that occurred when changing the number of cores for parallel computing in baramMesh has been fixed.
An error that occurred when configuring “Wall Layers” under the “Convection and Radiation” boundary condition for wall has been fixed.
An error that occurred when using JANAF for material property settings has been fixed.

Dynamic Mesh : It is now possible to simulate object motion. It supports three types of motion: Moving Cell Zone, which moves cell zones without mesh deformation; Moving Boundary, which moves boundary surfaces; and Rigid Body Dynamics, which considers the dynamics of rigid bodies and 6 degree of freedom motion.
Turbulent Transition model, Langtry-Menter 4 equation model : Supports a RANS-based turbulence model to predict the transition from laminar to turbulent flow.
Local Cylindrical Inlet Velocity Boundary Condition : It is now possible to specify axial, radial, and rotational velocities using the Local Cylindrical coordinate system in the Velocity Inlet boundary condition.
Temperature Profile Boundary Condition : It is now possible to set the spatial distribution of temperature.
Fan Boundary Condition : It is now possible to check and change the flow direction of the fan boundary conditions within the calculation domain.
MPI path setting : A path specification feature has been added to use BARAM’s own MPI instead of the system MPI in Linux.

There was an error where the initial conditions for turbulence were set higher than the input conditions. This error occurred in v26.1 and sometimes affected initial stability, and it has now been fixed.
The issue where it did not work properly when initializing pressure values in a specific area has been resolved.
There was an issue where Celsius temperature was not displayed in solid regions in Graphics, and this has been fixed.
Fixed an error where the y+ value was calculated incorrectly in Graphics.
Fixed an error where the Peng-Robinson condition was not working properly.
Fixed an error where, when monitoring was added after stopping the calculation, the added data was saved but did not appear in the graph.
Fixed an error that occurred when using the SST k-omega model in cases where there is no wall on the boundary surface.
