flow3d v9.4 2009 Releases (August 2009)
Distributed memory (MPI) parallel version FLOW-3D/MP 4.0:
•based on version 9.3.2 of the serial/SMP version
•CPU-optimized inter-block data transfer
•greatly reduced MPI communication
•automatic domain decomposition tool (ADT)
•scaling up to 32 ranks
Version 9.4 serial/SMP parallel:
•merged pre-processor and solver executables
•multi-species sediment scour and bed-load transport
•turbulence: reduce sensitivity to “turbulent mixing length”
•sand core gas model
•temperature-dependent fluid and solid component properties
•GMO model extensions
•non-linear Stokes wave model
•auto-termination at steady-state
•additional output for open channel (hydraulic) flows
•eliminates writing and reading intermediate files which can be several GB in size
•faster simulation startup
•easier code distribution and updates
•opens new possibilities to extend the restart logic:
multiple restart data source files flsgrf
multiple restart times
•simplifies code development
•no change in how the user runs simulation from the GUI and the command line
