====== Element failure ======

Volume element can be deactivated using a failure criterion. This criterion is applied on the ''FieldApplicator'' of [[doc:user:elements:volumes:volumeinteraction|volume elements]]. The criterion is defined as:

  rc = NamemRuptureCriterion()
  rc.put(param, value)
  rc.depend(param, fct, Field1D(Lock))
  ...
  app = FieldApplicator(no)        # association to the FieldApplicator number no
  app.push(1, SIDE_ID)
  app.addRuptureCriterion(rc)      

where
| ''NameRuptureCriterion''  | Failure criterion - see [[doc:user:elements:volumes:ruptureCritere]]  | 
|''param''  | name of one of the parameters (for example RUPT_CRIT_VAL)  |
|''value''  | value of the corresponding parameter   |
| ''fct''   | [[doc:user:general:fonctions]] whose property depend on (optional, no function if no dependency)  | 
| ''Field1D(Lock)''  | type of dependency of the corresponding property - see [[doc:user:elements:volumes:ruptureCritere]] (compulsory if there is a dependency)  |
