.TH "mkgeo_sector" 1rheolef "Version 7.2" "rheolef" \" -*- nroff -*- .ad l .nh .SH NAME mkgeo_sector \- mesh of a sector (rheolef-7\&.2) .PP .SH "SYNOPSIS" .PP .nf mkgeo_sector [options] n .fi .PP .SH "EXAMPLE" The following command build 2d unstructured mesh of the triangular region delimited by the three points (0,0), (1,0), (1,1): .PP .nf mkgeo_sector geo sector\&.geo .fi .PP .SH "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 \fCbamg\fP unstructured mesh generator\&. The mesh files goes on name\&.geo where \fIname\fP is the basename for the output (see option \fC-name\fP below)\&. The three auxiliary files required for automatic mesh generation with Rheolef combined with \fCbamg\fP are also provided: .PP .nf name\&.bamg name\&.bamgcad name\&.dmn .fi .PP .SH "THE GEOMETRY" The geometry is the triangular sector (0,0), (a,0), (a,b)\&. By default a=b=1\&. .PP \fC-a\fP \fIfloat\fP .br \fC-b\fP \fIfloat\fP .PP .RS 4 These options control the geometry parameters\&. .RE .PP .SH "THE DISCRETIZATION" The optional \fIn\fP argument is an integer that specifies the subdivision in each direction\&. By default n=10\&. .SH "BOUNDARY DOMAINS" The boundary sides are represented by domains: \fCaxis\fP, \fCboundary\fP, and \fCbisector\fP\&. .SH "OTHERS OPTIONS" \fC-name\fP \fIstring\fP .PP .RS 4 Set the basename for the output files\&. By default, the basename is \fCsector\fP\&. .RE .PP \fC-[no]clean\fP .PP .RS 4 Clear temporary files (this is the default)\&. .RE .PP \fC-[no]verbose\fP .PP .RS 4 In verbose mode, print to stderr all commands and logs\&. .RE .PP .SH "IMPLEMENTATION" This documentation has been generated from file main/sbin/mkgeo_sector\&.sh .SH AUTHOR Pierre Saramito .SH COPYRIGHT Copyright (C) 2000-2018 Pierre Saramito GPLv3+: GNU GPL version 3 or later .
