====== Definition of an ElementProperties ======

An ElementProperties  is defined with the lines:

  prp = ElementProperties(typeEl)
  prp.put(param1, valeur1)
  prp.depend(param1, fct1, Lock1)) # optional
  prp.put(param2, valeur2)
  prp.depend(param2, fct2, Lock2)  # optional
  ...

where

|''typeEl'' | type of finite element (for example ''Volume2DElement'') - see [[doc:user:elements:volumes:volumeelement|Volume element]] |
|''param1'', ''param2'' | code of the propriety relative to the element (for exéample ''MATERIAL'') - see [[doc:user:start#Eléments finis]] |
|''valeur1'', ''valeur2'' | "value" of the corresponding property |
|''fct1'', ''fct2'' | function which characterizes the dependency of the property  (optional: no ''fct'' if no dependency) |
|''Lock'' | [[doc:user:general:locks|Lock]] which defines the dependency variable of the property (compulsory if there is a dependency) |
