entityGenerator (1d, 2d, 3d)¶

Generates entities which can be used in defining regions for boundary conditions.

Parameters¶

onEntity (string): The entity generator will be a subset of the entity reference by onEntity. For boundary conditions this onEntity = ghost or a subset of ghost
newEntityName (string): The name of the newEntity that can then be used in updaters that are applied to entities.

Sub-Blocks¶

Function (block): Function which defines the entity. Wherever the function is positive and belongs the entity onEntity is defined the entity newEntityName will be defined.

Example¶

<Updater generateOpen>
  kind = entityGenerator2d
  onGrid = domain
  newEntityName = openBoundary
  onEntity = ghost
  <Function mask>
    kind = exprFunc
    exprs = ["if( (x>0.001) and (y>0.34),1.0,-1.0)"]
  </Function>
</Updater>
