IDENT

(required) how to handle the geometry part during point cloud organization

In the alias section, the IDENT identifier defines how boundary elements are treated during point cloud organization and in distance computation. It is used in AliasForGeometryItems statements. Example:
begin_alias{} "car" = " BC$...$ ACTIVE$...$ IDENT%IDENT_wall% MAT$...$ TOUCH%...% MOVE$...$ LAYER0 CHAMBER1 " end_alias
Default: Note:
  • The IDENT identifier DOES NOT describe the type of physical boundary condition. Physical boundary conditions are flagged by BC (see also %ind_BC%) and defined by BC_v, BC_p etc (see BoundaryConditions).
  • A definition depending on time or boundary element quantities is possible with IDENT statements.
  • The type of boundary associated to a MESHFREE point is found in %ind_kob% and can be visualized by
    SAVE_ITEM = (%SAVE_scalar%, [Y%ind_kob%], "IDENT")
  • For backwards compatibility, %IDENT_...% keywords hold the same value as their %BND_...% counterparts, and using IDENT%BND_wall%, IDENT%BND_inflow%, etc. will still work.
  • %IDENT_none% is the value of %ind_kob% of inner points in LIQUID and freely flying, non boundary points in DROPLETPHASE.
  • A list of all possible IDENT identifiers is found below.

Identifiers for boundary elements participating in the simulation

For regular geometries use Note: IDENT%IDENT_free% is used in initial filling to define the initial free surface for LIQUID. Whereas, %IDENT_ThinFilm% is used within DROPLETPHASE when in the initial filling phase a wall layer for LiquidLayer should be created.

Identifiers for postprocessing

For invisible geometries in INTEGRATION statements use IDENT%IDENT_BlindAndEmpty% is perfect for flux integrations, e.g. %INTEGRATION_FLUX%, and monitor point creation with %MONITORPOINTS_CREATION_PenetrationOfBlindAndEmptyBoundary%.
