ExtractMaterials

Description

This tool takes a mesh with multiple material IDs and writes elements of a specific ID to a new mesh. If no ID is specified, meshes are created for each existing material ID.

Usage

USAGE: 
   ExtractMaterials  -i <input file name> -o <output file name> 
                      [-m <Number specifying the MaterialID>] 
                      [--] [--version] [-h]

Where: 

   -i <input file name>,  --input <input file name>
     (required)  Name of the input mesh (*.vtu)

   -o <output file name>,  --output <output file name>
     (required)  Name of the output mesh (*.vtu)

   -m <Number specifying the MaterialID>,  --material-id <Number specifying
      the MaterialID>
     The MaterialID for which elements should be extracted into a new mesh.

   --,  --ignore_rest
     Ignores the rest of the labeled arguments following this flag.

   --version
     Displays version information and exits.

   -h,  --help
     Displays usage information and exits.

Example:

In this example we use a 3D mesh (Fig.1) and extract its elements of material ID 3 to create a new mesh.

ExtractMaterials -i mesh_layered.vtu -o mesh_exMatId.vtu -m 3

Fig.1 The left side shows a layered 3D input mesh created from raster files using the tool createLayeredMeshFromRasters. The different colors depict different material IDs. The z-values of the meshes are scaled by a factor of 10. The right mesh shows the extracted mesh. In this graphic it is translated along the x-axis, its spatial coordinates are not altered by the ExtractMaterials-tool.
