bamg2geo - convert bamg mesh in geo format (rheolef-7.2)

bamg2geo [options] file[.bamg] file[.dmn]

Convert a .bamg file into a .geo one. The output goes to standard output. The .dmn file specifies the domain names, since the bamg mesh generator uses numbers as domain labels instead of names. When no files are provided, the standard input is used.



    bamg -g toto.bamgcad -o toto.bamg


    bamg2geo toto.bamg toto.dmn > toto.geo

The .bamgcad file describes the boundary of the mesh geometry. Here is a basic example:



    MeshVersionFormatted


      0


    Dimension


      2


    Vertices


      4


      0  0     1

See bamg(1) .

The .dmn file defines the boundary domain names used by Rheolef, since bamg uses numeric labels for domains. Here is an example:



    EdgeDomainNames


      4


      bottom


      right


      top


      left


The domain name file can also specify additional vertices domain:



    EdgeDomainNames


      4


      bottom


      right


      top


      left


    VertexDomainNames


      4


      left_bottom


      right_bottom


      right_top


      left_top


Vertex domain names are useful for some special boundary conditions.

-cartesian
-rz
-zr


Specifies the coordinate system. The default is cartesian while -rz and -zr denotes some axisymmetric coordinate systems. Recall that most of Rheolef codes are coordinate-system independent and the coordinate system is specified in the geometry file .geo.
