AliasForGeometryItems

alias definitions for geometry parts

All names of geometry parts need to be assigned to special aliases. There are multiple options to deal with the name of a geometry part:

Explicit assignment of properties to full names of geometry parts
- Declare full properties as explained below. Example:
  
  begin_alias{} "car" = " BC$BC_box$ ACTIVE$noinit_always$ IDENT%BND_slip% MAT$Mat1$ TOUCH%TOUCH_liquid% MOVE$MOVE_car$ LAYER0 CHAMBER1 " # full description end_alias
- Assign properties of another alias. Example:
  
  begin_alias{} "windshield" = "&car&" # reference to alias car end_alias
Automatical choice of properties based on patterns
- Similar to 1, but matching multiple names with a wildcard. The wildcard-option is tried ONLY, if no direct match with the given aliases can be stablished. In this case, each of the matched names is available in postprocessing. Example: Names in geometry file: WheelFrontLeft, WheelFrontRight, WheelBackLeft, WheelBackRight
  
  begin_alias{} "Wheel*" = "&car&" # reference to alias car "*" = " BC$BC_box$ ACTIVE$noinit_always$ IDENT%BND_slip% MAT$Mat1$ TOUCH%TOUCH_liquid% MOVE$NO_MOVE$ LAYER0 CHAMBER1 " # full description end_alias
- Using the DEFAULT properties for any group of names not specified via the options above. The alias-name-definition has to contain "_DEFAULT" at the end. See also __DEFAULT_configuration_file__ . Example:
  
  begin_alias{} "in*_DEFAULT" = "&car&" # reference to previously defined alias car end_alias
  
  For all those matching a DEFAULT-item, MESHFREE attaches "_DEFAULT" as a suffix to the given name from the geometry input, such that it can be recognized easily as DEFAULT-defined. The geomtry item "inflow1", matching the alias "in*_DEFAULT", will be named "inflow1_DEFAULT" for postprocessing.
- DEPRECATED: Using default properties for any names not specified via the options above. All these names will be replaced by 'default'. Example:
  
  begin_alias{} "default" = "&car&" # reference to alias car end_alias
  
  Instead of "default", use "*_DEFAULT" in order to have a general default definition, that matches ALL geometry.
