duplicate{

Duplicate part of the geometry and apply a new alias. By default, the orientation of the duplicated geometry is inverted for use with a second chamber. If the original orientation is required, this can be achieved with an extra call to revOrient{}.

Note: The aliases of the duplicated geometry have to be defined as usual (see AliasForGeometryItems). This means, flags such as BC, ACTIVE, IDENT, etc. are not inherited from the original geometry.

• With inverted orientation for use with a second chamber (duplicate geometry with alias "sphere" and apply alias "bubble"):

  begin_boundary_elements{} include{sphere.msh} # contains alias "sphere" manipulate{"sphere"} duplicate{"bubble"} end_boundary_elements

• With original orientation for a translated copy of the geometry with different alias (step 1 - duplicate geometry with alias "cube" and apply alias "cube_offset", step 2 - restore original orientation and translate alias "cube_offset"):

  begin_boundary_elements{} include{cube.msh} # contains alias "cube" manipulate{"cube"} duplicate{"cube_offset"} manipulate{"cube_offset"} revOrient{} offset{0,0,1} end_boundary_elements
