(Return)
The translator creates grid files and boundary condition file for USA from a
structured mesh.
Creating the USA Files
The translator writes the USA files using structured domain files and the
corresponding topology file. To create the USA input files, select the
translator "USA" in the "Output" menu from the ICEM CFD/CAE Manager. After
clicking "Write output" you can specify options for the USA interface:
-
select existing multiblock mesh
-
specify if the grid files are ASCII or binary (default is binary)
-
give the name of the topology file
-
give the prefix name of the USA files
The interface generates for each block a grid file and one boundary condition
dataset located in the project directory:
-
prefix.n : grid file of block n
-
prefix.bc : boundary condition dataset
-
prefix.log: log file
Defining Boundary Conditions for USA
The following boundary conditions are supported for this interface:
-
User specfied bc (UBC)
-
Adiabatic wall (ADI_W,100)
-
Inviscid wall (INV_W,110)
-
Symmetry (SYMM,120)
-
0-Fluxes (0_FLX,130)
-
EXTR(QCEN) (EXTQC, )
-
EXTR(QFIN) (EXTQF,150)
-
FREEZE DEP (F_DEP,160)
-
Periodic (PEROD,170)
-
Isothermal wall (ISOTW,200)
-
Fix conservative Q vector (FIX_C,300)
-
Char. theory, QCEN, CONSVAR (THQCC,310)
-
Char. theory, QFIN, CONSVAR (THQFC,320)
-
Fix primitive Q vector (FIX_P,400)
-
Char. Theory QCEN, PRIM (THQCP,410)
-
Char. Theory QFIN, PRIM (THQFP,420)
-
Aligned Zonal bc(coupled, subsonic) (ZON_A,500)
-
Unaligned zonal bc (ZON_U,600)
Interfaces between blocks are handled such that a BC Number 500 is assigned to
interfaces between blocks in the same family, and a BC Number of 300 is
assigned to interfaces between blocks in different families.
