.SH NAME
\fBmkgeo_sector\fP -- build an unstructured 2d mesh of a sector

.SH EXAMPLE

The following command build 2d unstructured mesh
of the triangular region delimited by the three points (0,0), (1,0), (1,1):
.\" begin_example
.Sp
.nf
        mkgeo_sector
        geo sector.geo
.Sp
.fi
.\" end_example
.SH DESCRIPTION

.\" skip: @pindex bamg
This command is convenient for building a mesh for
a sector, as it is a very classical benchmark in complex
fluid flow problems.
It calls \fBbamg\fP unstructured mesh generator.
The mesh files goes on `\fB@var{name'\fP.geo} where \fIname\fP
is the basename for the output (see option \fB-name\fP below).
The three auxiliary files required for automatic mesh generation
with Rheolef combined with \fBbamg\fP are also provided:
`\fB@var{name'\fP\fB.bamg\fP},
`\fB@var{name'\fP\fB.bamgcad\fP} and
`\fB@var{name'\fP\fB.dmn\fP}.
.SH THE GEOMETRY

The geometry is the triangular sector (0,0), (a,0), (a,b).
By default a=b=1.
.\" begin table
.\" start item
.TP
.B -a \fIfloat\fP
.\" start item
.TP
.B -b \fIfloat\fP
These options control the geometry parameters.
.\" end table
.SH THE DISCRETIZATION

The optional \fIn\fP argument is an integer
that specifies the subdivision in each direction.
By default \fIn\fP=10.
.SH BOUNDARY DOMAINS

The boundary sides are represented by domains: \fBaxis\fP, \fBboundary\fP,
and \fBbisector\fP.
.SH OTHERS OPTIONS

.\" begin table
.\" start item
.TP
.B -name \fIstring\fP
Set the basename for the output files.
By default, the basename is \fBsector\fP.
.\" start item
.TP
.B -clean
.\" start item
.TP
.B -noclean
clear temporary files (this is the default).
.\" start item
.TP
.B -verbose
.\" start item
.TP
.B -noverbose
In verbose mode, print to stderr all subcommands and logs.
.\" end table
