# 2.4. Version 5.22 (2024/10/08)

Bug Fixes:

  - Fixed inconsistent heat loss variable computation in some circumstances, for instance at walls with intermediate values of mixture fraction.

New Features

  - Wall-modeled LES (WMLES) exchange-based approach for momentum and energy turbulent boundary conditions are fully supported. Exchange distance remains user specified.

  - New “USE NEUMANN CONDITION FOR KSGS” line command that should be activated when using the WMLES k-sgs model to avoid conflation of “subgrid-scale kinetic energy” with “turbulent kinetic energy”.

Change in Behaviors

  - Consistent WMLES usage of wall friction velocity when the “DETERMINE UTAU VIA NONLINEAR LAW OF THE WALL ITERATION” line command is activated.
