mkgeo_sector(1rheolef) rheolef mkgeo_sector(1rheolef)

NAME

mkgeo_sector - mesh of a sector (rheolef-7.2)

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 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

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.

-[no]clean


Clear temporary files (this is the default).

-[no]verbose


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