      EntitiesByCondition()

      Returns all entities for which the specified boolean condition is evaluated as True (for example, a static signal value comparison).

      Syntax

      EntitiesByCondition(expression)
      • expression: one or more boolean expressions

      EntitiesByCondition() can combine multiple boolean expressions with and/or constructs (see examples). Mathematical operators that are allowed include

      • = (equals)
      • <= (less than or equal to)
      • >= (greater than or equal to)
      • <> (not equal to)

      Examples

      EntitiesByCondition("porosity" in "%" = 42.67)

      EntitiesByCondition("porosity" in "%" >= 1.2 And "permeability" in "m2" <= 21.7)

      EntitiesByCondition("porosity" in "%" >= 1.2 Or "permeability" in "m2" <= 21.7)

      EntitiesByCondition(
          "porosity" in "%" >= 1.2 And
          ("permeability" in "m2" = 21.7 Or "permeability" in "m2" = 42.1)
      )   

      EntitiesByCondition("porosity" in "%" <> 17.3)

      EntitiesByCondition(IsNotNull("porosity" in "%"))

      EntitiesByCondition(IsNull("permeability" in "m2"))

      More Examples

      Entity Set "Montney Wells"
          EntitiesByCondition(Contains("primary formation" in " ", "montney")
          Or Contains("primary formation" in " ", "mntny"))
      End Set
      Entity Set "Upper Montney Wells"
          EntitiesByCondition("primary formation" in " " = "TRmntny_U")
      End Set
