VULCAN (Viscous Upwind ALgorithm for Complex Flow ANalysis) is a turbulent, non-equilibrium, finite-rate chemical kinetics, Navier-Stokes flow solver for structured, cell-centered, multi-block grids that is currently maintained and distributed (restricted to US) by the Hypersonic Airbreathing Propulsion Branch of NASA Langley Research Center.
The ANSYS ICEM CFD - VULCAN output interface writes a multiblock grid file
and a VULCAN input file. The multiblock grid file is written in the
Plot3D multiblock grid file format, in Fortran free format (ASCII).
The grid can be written in single or double precision and the grid file
name gets the extension ".grd". The boundary conditions and interblock
connectivity are written in the VULCAN input file format. The input file
name gets the extension ".dat". This file is a subset of the complete
Vulcan input file. Data such as solver control parameters can be
added in the VULCAN User Interface.
The VULCAN boundary conditions supported by this interface are:
EXTRAP, EXTRAP2, REGOUT, REGOUT2, SYMM, REFFIX, AXICL, SWALL,
AWALL, AWALLM, SINGULAR, FIXED, IWALL, IWALLM, TCWALLM,
SUBMDOTI, SUBIN, SUBOUT
Note that BC NAME is limited to 10 characters in VULCAN.
Once all boundary conditions have been assigned , the VULCAN output interface can be launched. Under the Output menu, select Write Input. A window will open to allow the specification of the files that will be translated into the VULCAN format. Default names for the topology, boundary condition and VULCAN files will show up. These can be modified as necessary. The translator will add the suffix ".grd" and ".dat" to the VULCAN mesh and input files.
The interface generates the VULCAN files in the current project directory.
