bamg: bidimensional anisotropic mesh generator

NAME

bamg - bidimensional anisotropic mesh generator

SYNOPSIS

bamg options -g input[.bamgcad] -o ouput[.bamg]
EXAMPLE
bamg -g toto.bamgcad -o toto.bamg
OUTLINE OF THE COMMANDS
This software can create a mesh from a geometry adapt a mesh from a background mesh using a metric or solution file do smoothing to make quadrilaterals and to split internal edge with 2 boundary vertices in an existing mesh (in this case the metric is use to change the definition of the element's quality). construct just a metric file, if you have an other mesher do the P1 interpolation of the solution on another mesh:

CREATE A MESH FROM A GEOMETRY

input file with -g filename (file type DB mesh). output file arguments -oxxxx filename where xxxx is the type of output file (see below for more details). smoothing, quad, utility and other parameters. In addition, metric specication may be prescribed with the help of -M filename argument (file type Metric). All the options are described below.

ADAPT A MESH FROM A BACKGROUND MESH USING A METRIC OR SOLUTION FILE

input files -b filename where the suffixe of the file define the type of the file '.amdba', '.am_fmt', '.am', '.ftq', '.nopo' and otherwise the file is a BD mesh file. input '-M filename' (file type Metric) or -MBB filename or -Mbb filename (solution file type BB or bb). metric control parameters, -err val, -errg val,.... output file arguments reqired interpolation, smoothing, quad, utility parameter, and other parameter do smoothing, to make quadrilaterals: and to split internal edge with 2 boundary vertices in an existing mesh (in this case the metric is use to change the definition of the element's quality). input files -r filename(file type DB mesh). -M filename (file type Metric). output file -o filename (file type DB mesh). some other parameter: @table @code -thetaquad val: to create quad with 2 triangles -2: to create the submesh with mesh size h = h/2 -2q: to split all triangles in 3 quad. and to split all quad. in 4 quad. -NbSmooth ival: to change the number of smoothing iteration (3 by default if the metric eld is set with arguments : -M or -Mbb, 0 otherwise. ... @end table construct just a metric file, if you have an other mesher: input files -r filename (file type DB mesh). --Mbb filename or -MBB filename + all the arguments of the metric construction output file -oM filename (file type Metric). do the P1 interpolation of the solution on another mesh: input files -r filename (file type DB mesh). --rBB filename or -rbb filename output file -wBB filename or -wbb filename BAMG(1)
