User defined post-processing interval
VEC5-1610
The user now has the ability of changing the frequency of the post-processing writes so that they
get more information in key regions and less information in others.
Extend LAMINAR FLAME SPEED MODEL to use user-defined
models
VEC5-1561
A user function option for specifying laminar flame speed has been added. It can be invoked by
specifying a new block in the input file.
More information and general setup can be found in the user manual.
Create rs-mpi for versions LAM 7.1.2 and LAM 7.1.4
RSMPI-19
A problem was detected with the VECTIS solver (phase5) as it is linked with LAM711. It has been
addressed by dynamically linking with Intel libraries instead of statically linking.
Disable diagnostic message generated by RV5\_Porous\_Cell
user function
VEC5-1655
Diagnostic messages generated by the RV5_Porous_Cell user function must now be activated by
setting the environment variable RV5_USER_DEBUG to 2 or greater.
Implement OR and AND operations for user functions
VEC5-1687
Two new functions have been added to the user functions access library:

Global_SUML_AND – reduces the logical variable passed to it over all parallel domains
with the AND condition (i.e. the result returned is True if the variable is True for all
processes and False otherwise). In C binding, the integer type is used instead of the
logical type.

Global_SUML_OR – reduces the logical variable passed to it over all parallel domains with
the OR condition (i.e. the result returned is True if the variable is True for at least one
process and False otherwise). In C binding, the integer type is used instead of the logical
type.
Allow user functions to be built using the "umake" script
VEC5-1685
Allow user functions written in FORTRAN and C/C++ to be built using the "umake" utility. On
Windows, automatically build serial and parallel versions of the user function.
Corrections
Combustion model terminates for G-eq/Multi-Cycle run
VEC5-1519
It was reported that multi-cycle simulations with G-equation combustion model stopped in the
second cycle if the ignition started at a position near the end of the first cycle. This has been
addressed.
Auto-ignition observed in intake/exhaust port
VEC5-1595
Auto-ignition was observed in intake or exhaust ports due to changes related to CPV models 3-6.
This has been addressed.
