NAME

mkgeo_sector -- build an unstructured 2d mesh of a sector

SYNOPSIS

  mkgeo_sector options [n]

EXAMPLE

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

DESCRIPTION

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 bamg unstructured mesh generator. The mesh files goes on `@var{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: `@var{name'.bamg}, `@var{name'.bamgcad} and `@var{name'.dmn}.

THE GEOMETRY

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 DISCRETIZATION

The optional n argument is an integer that specifies the subdivision in each direction. By default n=10.

BOUNDARY DOMAINS

The boundary sides are represented by domains: axis, boundary, and bisector.

OTHERS OPTIONS

-name string

Set the basename for the output files. By default, the basename is sector.

-clean

-noclean

clear temporary files (this is the default).

-verbose

-noverbose

In verbose mode, print to stderr all subcommands and logs.
