mkgeo_sector [options] n
The following command build 2d unstructured mesh of the triangular region delimited by the three points (0,0), (1,0), (1,1):
mkgeo_sector geo sector.geo
This command is convenient for building a mesh for a sector of a square pipe section, as it is a very classical benchmark in complex fluid flow problems. It calls bamg
unstructured mesh generator. The mesh files goes on name.geo where name is the basename for the output (see option -name
below). The three auxiliary files required for automatic mesh generation with Rheolef combined with bamg
are also provided:
name.bamg name.bamgcad name.dmn
The geometry is the triangular sector (0,0), (a,0), (a,b). By default a=b=1.
-a
float
-b
float
These options control the geometry parameters.
The optional n argument is an integer that specifies the subdivision in each direction. By default n=10.
The boundary sides are represented by domains: axis
, boundary
, and bisector
.
-name
string
Set the basename for the output files. By default, the basename is
sector
.
-[no]clean
Clear temporary files (this is the default).
-[no]verbose
In verbose mode, print to stderr all commands and logs.
